Ray Gwinn's comm drivers for OS/2, V1.40.
SIO.SYS and VSIO.SYS are replacements of the
OS2 communications drivers COM.SYS and
VCOM.SYS which come with OS/2. VX00.SYS
provides FOSSIL and virtual 16550 support
for DOS programs SIO can be ordered to
supporting any number of ports. Now has a
virtual modem for Internet access.

To Install SIO, change to the disk and directory containing the
(unziped) SIO distribution files and type INSTALL, followed by
return.

This release of SIO (V1.40) contains corrections and additions to
the basic code. See HISTORY.TXT in the distribution zip for
details. The on line SIO documentation files (.INF) are not
included in this release of SIO. Insufficient time was available
to update the on line documentation.

PCMCIA modem users that added RESERVE.SYS to their CONFIG.SYS for
SIO 1.35 should now remove the statement. The SIO install
program will REM out that statement automatically.

SIO has been tested on OS/2 V3.0 and seems to work without
changes or additions. This version of SIO contains additions
that make SIO Resource Manager compliant.

Windows better than Windows! If you are using COMM.DRV from
Windows for Workgroups 3.11, SIO will now support the
communications directly. That is, Windows programs will be
directly supported by SIO proper, and the virtualization that
existed in earlier versions of SIO is bypassed. In this
environment, Windows communications programs should work as well
as native OS/2 communications programs. Thanks to Rob Rose of
IBM for some critical information about the Windows
communications interface.

The SIO support BBS is now available via Internet using VMODEM or
Telnet. The Internet address is 199.248.240.2.

VMODEM version 1.00 is included in this release of SIO.
VMODEM.EXE is a virtual modem implementation that allows serial
communications programs to work over the Internet. VMODEM also
includes a Telnet server. VMODEM allows virtually any data
communications program, including your favorite BBS software, to
use an Internet connection instead of a telephone line. Several
existing BBSes and now accessible via Internet. Most took only
about 5 to 10 minutes to setup under VMODEM. I wonder if
Internet is ready for the explosion that is about to come.

VMODEM.EXE was developed and tested under IBM's TCP/IP Version
2.0 with the August 1994 CSD applied, and has been tested with
the Internet Access Kit (IAK) that is included in the bonus pack
of OS/2 V3. However, your are on your own with respect to any
setup of TCP/IP.
