- Notes for Revision 5.0

If you have just acquired the shareware version of the LiteComm(tm)
Toolbox, try the QBTTL sample program and look over its code, feel free
to experiment with the functions and, if you like what you see, please
register and join our list of satisfied users from all over the world.

If you've registered LiteComm, thank you. Your registration helps make
it possible for us to continue supporting and enhancing the product.

REGISTERED USERS PLEASE NOTE:
The serial number of your copy is found on the diskette label, not in
the lserial.num file as mentioned in the documentation.

With Revision 5.0, the most critical portion of the kernel, we have
further reduced the code in the interrupt handler which not only reduced
the size of this critical section, but allowed further savings in other
areas. See the documentation section "New in Version 4.0" for
additional details.

NOTE CAREFUULY!!!
If you have used LiteComm before, it will be necessry for you to
re-compile and relink your applications, primarily do to changes that
we instituted in the Communications Control Block (CCB).

You should not have to modify the any of the source code to compile it
on any of the supported compilers. Extensive use of C preprocessor
statments has been made to insure that all modules will compile under
any of the supported compilers with no additional effort.

With version 5.0, we have dropped the library-only registration class,
largely due to the fact that more than 97 per cent of all registrants
obtain the source code. All library-only registrants will be
automatically eligible for a no-charge upgrade to the full source
version on payment of the $10 upgrade fee which all registrants must
pay to upgrade to the latest version of LiteComm.

We have also provided a complete set of "make" files to assist you in
rebuilding the libraries, should it become necessary, or should you
wish to modify the supplied routines. Be cautious...the make files, at
a minimum, assume that you have both ARC and LIB available in either
your current working directory or somewhere in the current path. Note
also that you MUST have available either MASM 5.X or Turbo Assembler
version 1.0 or greater.

LiteComm is an advanced product for advanced users. Due to the various
conditions under which LiteComm might be used, we have not attempted to
provide you with specific instructions on linking the LiteComm libraries
with your application programs. We assume that you are familiar with
the methods needed to link third-party libraries, such as LiteComm, with
your applications. Answering specific questions regarding linking of
LiteComm to any given application is not practical, since it requires
specific knowledge of how your system is organized, and of your
application that cannot generally be obtained by telephone.

DOCUMENTATION CHANGES
---------------------

In the process of developing the documentation for the new
BBS(so-called) functions a few pieces of information were inadvertantly
omitted. We provide this additional information below as an assist to
your use of the new functions.

Note that to use the lcbbs functions, you must include as a part of
your link the xmodem library, since the lcbbs functions use one of that
library's component function to purge the receive buffer. The purge
function is a 1 second, timed wait for input that returns when 1 second
has elapsed with no input received during that period. Any input that
is received is discarded. In addition, it will be necessary for you to
use the lc_insclock function (see the documentation) to properly install
a clock handler. If you do not install a clock handler, the purge
function will either behave erratically or will, at worst, cause your
system to hang. Alternatively, if you wish, you may write your own
purge function using the event timers included in the new functions.
For shareware users, this will be mandatory, since we do not intend to
alter our distribution policy. As an aid, we have include a sample
purge function below that you might want to use.

/*
** sample purge function
*/
#include "litecomm.h"
#include "lcbbs.h"

void purge(port)
{
long purge_ev;

purge_ev = new_event(1);/* 1 second timer */
while (1)
{
if (lc_get(port) == -1)/* got a character? */
if (! check_event(purge_ev)) /* ZERO if expired */
return;
else
continue;/* timer did not expire */
/*
** we got a character, reset the timer so
** that there is another 1 second timeout
*/
purge_ev = new_event(1);/* 1 second timer */i
}
}


/*
** These are sample strings to be sent for
** modem initialization. They must be customized
** to suit the inividual modem

char MODEMSET0[] = "ATZ\r";
char MODEMSET1[] = "ATT E0\r";
char MODEMSET2[] = "ATC1 V0 X1 S0=1 M1\r";

** corresponds to
**Reset
**Touch Tone Dialing, Command Echo off *
**Carrier off/detect carrier
**Numeric codes *
**Hayes extended set
**answer on first ring
** enable the speaker
**
** starred items are needed at a minimum
