CHAPTER 21 DIRECTORY OF KERMIT COMMANDS

All the commands in this directory are entered from VTERM's local
Kermit prompt. The portions of the command in parentheses may be
omitted; only those characters necessary to distinguish one
command from another need be entered.

Alt-A
Press Alt-A to abort file transfer immediately. If a group of
files is being transferred with a wildcard command, Alt-A aborts
transfer of the entire group without waiting for an acknow-
ledgment from the host.

Alt-Q also aborts transfer of a group of files but does so in an
orderly way, waiting for the proper acknowledgment from the host.

To abort transfer of only one file in a group, use Alt-X.

Generally speaking, use Alt-A only when it is unlikely that AltDQ
will work -- for example, when no packets seem to be getting
through, or when the rate of resends is very high.

Note: Pressing Alt-S or the hot key during a transfer causes the
same action as pressing Alt-A.

Alt-H
Press Alt-H to display VTERM's help screens.

Alt-K
Alt-K makes VTERM toggle between its local Kermit prompt and its
regular Terminal Screen.

If you press Alt-K from the regular Terminal Screen, VTERM's
local Kermit prompt appears and VTERM starts acting like a Kermit
machine. If you press Alt-K from VTERM's local Kermit prompt,
the prompt disappears and VTERM behaves like an ordinary terminal
again.

VTERM has a softkey command, , that causes it to enter Kermit
Mode. The effect is the same as pressing Alt-K from the regular
Terminal Screen. For further information on softkey commands,
see Part 2 of the Evaluation Kit.

Alt-Q
Press Alt-Q to abort file transfer in an orderly way. If a group
of files is being transferred with a wildcard command, Alt-Q
aborts transfer of the entire group after notifying the host that
the receiving computer should discard the file currently being
transmitted.

To abort transfer of only one file in a group, use Alt-X.

To abort a group transfer immediately, use Alt-A, Alt-S, or the
hot key.

Alt-S
Press Alt-S to display VTERM's setup screens.

Note: If you press Alt-S during a file transfer, the transfer is
aborted immediately, just as if you pressed Alt-A.

Alt-Y
Press Alt-Y to resend whatever packet was most recently sent to
the host. You might do this, for example, when the host is so
slow in responding that you suspect your last transmission did
not get through.

You can resend any particular packet repeatedly with Alt-Y, up to
the number of times selected for Outgoing Max Retries on Setup
Screen Two.

Alt-X
Press Alt-X to abort transfer of a single file. If a group of
files is being transferred with a wildcard command, Alt-X aborts
transfer of only the file currently being transmitted.

To abort transfer of an entire group, use Alt-A or Alt-Q.

BYE or LOGO(UT)
Use only when connected to a server.

The BYE or LOGOUT command tells the host server to terminate
itself and log out its job.

COL(LISION)
The COLLISION command specifies what VTERM should do when it
receives a file with the same name as an existing file. The
command has four forms:

þ COL(LISION) by itself shows which of the following three options
is currently selected.

þ COL(LISION) O(VERWRITE) erases the existing file and
saves the new one.

þ COL(LISION) REN(AME) renames the new file to avoid confusion with
the existing one.

VTERM renames the new file by replacing the rightmost
character of the extension with a zero. For example,
SAMPLE.TXT becomes SAMPLE.TX0. If that name already exists,
VTERM uses 1, then 2, then 3, and so on up to 999.

þ COL(LISION) P(ROMPT) prompts you for instructions when the time
the file is received, giving you the option of aborting,
overwriting, or renaming.

CON(NECT)
This command causes VTERM to return to Terminal
(non-Kermit) Mode.

Ctrl-Break
This command terminates VTERM entirely (without keeping it
resident in memory) and returns to PC-DOS.

Enter
You must press the Enter key to make Kermit act on a command.

EO(F)
The EO(F) command determines how VTERM treats Ctrl-Z characters at
the end of files. (Ctrl-Z is the normal terminating character in
DOS text files.) There are three options:

þ EO(F) by itself shows which of the following two options
is currently selected.

þ EOF C(TRLZ). When VTERM is sending a file and encounters
a Ctrl-Z, it stops sending the file and does not send the Ctrl-Z.

When VTERM is receiving a file, it appends a Ctrl-Z to the
end of the file if it lacks one; otherwise, it receives the
exactly as it is.

þ EO(F) N(OCTRLZ). VTERM sends and receives files exactly as
they are without changing the end-of-file characters.

The effects of the two options are summarized in the
table in Figure 21-1.
__________________________________________________________
EOF CTRLZ EOF NOCTRLZ
__________________________________________________________
When Stop at first Ctrl-Z Send file exactly
Sending don't send it or as it is.
File following characters.

When Append Ctrl-Z at end Receive file
Receiving of file if it lacks one; exactly as it is.
File otherwise receive file
exactly as it is.

Figure 21-1. Kermit EOF Options

Esc
Press the Escape (Esc) key to cancel a command line.

EX(IT)
The EX(IT) command causes VTERM to terminate, just as if you
pressed Ctrl-Break. No message will be sent to the host to
inform it that this has happened.

F(INISH)
Use this command only when connected to a server.

The F(INISH) command tells the server to terminate itself, but not
to log out its job.

G(ET)
Use G(ET) only when connected to a server.

The G(ET) command tells the host server to send a file to your PC.
The file is designated by , the file's name on
the host system. The same name is automatically used for the
downloaded file on the PC.

To download a file from a host system that is not in server mode,
use the REC(EIVE) command.

Hot Key
See VTERM Hot Key at the end of this file.

I(NITIALIZE)
Use this command only when connected to a server.

The I(NITIALIZE) command is very rarely needed. It causes an
exchange of init packets between VTERM and the remote Kermit host
software. Normally, such an exchange is carried out auto-
matically when file transfer is initiated. For more information,
see the Kermit User Guide published by the Columbia University
Center for Computing Activities.

LOGI(N)
This command invokes the login function on the host.

LOGO(UT)
This command disconnects from host. It has the same effect as BYE.

Q(UIT)
Q(UIT) causes VTERM to switch from the local Kermit prompt to
Terminal Mode. It can be used to redisplay the remote Kermit
prompt. The CON(NECT) command has the same effect.

REC(EIVE)

REC(EIVE) tells VTERM to download a file from the host. (You must
enter a separate command at the remote prompt to tell the host to
send the file.) If the host can operate in Server Mode, it is
more convenient to download with the G(ET) command.

With most host Kermits, entering REC(EIVE) at the remote prompt
causes the host to receive a file to your PC. You use REC(EIVE) in
this way (after entering SE(ND) from the local prompt) to upload to
a system that is not in Server Mode.

REM(OTE) COPY
Use only when connected to a server.

The REM(OTE) COPY command tells the host to copy the file or files
from the to the . Both
the source and destination must be on the host system.

REM(OTE) CW(D)
Use only when connected to a server.

The REM(OTE) CW(D) (change working directory) command tells the
server to change its current directory for file operations to the
specified . When used without an argument, it
tells the server to change to the directory which was the default
at the time the host Kermit program was invoked.

REM(OTE) DEL(ETE) or REM(OTE) ER(ASE)
Use only when connected to a server.

The REM(OTE) DEL(ETE) or REM(OTE) ER(ASE) command tells the server to
delete the file or files indicated by . The file
specification is passed to the host and may contain any wildcard
characters supported by the host.

REM(OTE) DIR(ECTORY)
Use only when connected to a server.

The REM(OTE) DIR(ECTORY) command tells the server to send a directory
listing, which VTERM will display. The optional is
passed to the host and may contain any wildcard characters
supported by the host.

REM(OTE) DIS(K) or REM(OTE) SP(ACE)
Use only when connected to a server.

These commands tell the host to display disk usage and disk
availability information in the directory specified, or in the
current or default area if you do not specify the
argument.

REM(OTE) ER(ASE)
See the command REM(OTE) DEL(ETE) described above.

REM(OTE) HE(LP)
This command calls up the host system's help facility.

REM(OTE) HO(ST)
Use only when connected to a server.

The REM(OTE) HO(ST) command is not available on most servers. On
systems that do support it, the argument is passed to
the host command processor for execution.

REM(OTE) MES(SAGE)
Use this command only when connected to a server.

The REM(OTE) MES(SAGE) command tells the host server to pass the
specified to the screen of the user designated by
.

REM(OTE) REN(AME)
Use only when connected to a server.

This command tells the server to rename the file or files
described by the . The file specifications may
contain any wildcard characters supported by the host.

REM(OTE) SP(ACE) or REM(OTE) DIS(K)
Use only when connected to a server.

These commands tell the host to display disk usage and disk
availability information in the directory specified, or in the
current or default area if you do not specify the
argument.

REM(OTE) TY(PE)
Use only when connected to a server.

The REM(OTE) TY(PE) command tells the host server to display the
contents of the specified file or files on the VTERM screen. The
is passed to the host and may include any wildcard
characters that the host will recognize.

REM(OTE) W(HO)
Use this command only when connected to a server.

The REM(OTE) W(HO) command tells the server to provide information
about who is logged in on the host system. The optional
parameter specifies that information is only requested about a
particular user, or about a particular computer within a network.

SE(ND)
When entered from the local Kermit prompt, this command transfers
a file from your PC to a host. The file is designated by filespec>, the file's name on your PC.

The is the name applied to the copy of the file
received by the remote computer. If you do not specify a filespec>, the is automatically used as the name
of the file on the other computer.

If you are uploading to a host that is not in Server Mode, you
must enter a command at the remote prompt that tells the host to
receive the file. On most host Kermit systems, this command is
REC(EIVE).

With most host Kermits, entering SE(ND) at the remote prompt will
cause the host to send a file to your PC. You use SE(ND) in this
way (after entering REC(EIVE) at the local prompt) to download from
a system that is not in Server Mode.

TA(KE)
If you have a series of Kermit commands which you often repeat in
sequence, you can store those commands in a normal DOS file and
execute them automatically with the TA(KE) command. You can create
such a command file just as you would create a DOS .BAT file,
with the copy command or with a text editor.

Once you have created the command file, you can enter the TA(KE)
command at the local Kermit command prompt, followed by the name
of the command file, including any disk, path specifiers and
extension. The commands in the file are then executed, echoing
to the screen in the process.

TR(ANSLATE) ON or OF(F)
This command is intended primarily for users of VTERM in foreign
language environments. When TR(ANSLATE) is ON, VTERM translates
certain foreign language characters during file transfer. When
TR(ANSLATE) is OF(F), VTERM sends or receives the file exactly
as it is.

For text file transfers, you probably want TRANSLATE ON. For
binary file transfers, you probably want it OFF.

VTERM Hot Key
The hot key (both Shift keys simultaneously unless configured
differently in V2CONFIG) toggles between VTERM and DOS. If you
press the hot key during a Kermit session, you leave VTERM and
enter DOS. You can then run a DOS utility or a local program on
your PC.

When you press the hot key a second time, you re-enter VTERM.
You are still in Kermit and on-line with your host, and the VTERM
screen looks exactly the way it did before you pressed the hot
key the first time.

If you press the hot key while transferring a file, the transfer
is immediately aborted. When you later press the hot key to re-
enter VTERM from DOS, you return to VTERM's local Kermit prompt.

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
