For those who might not have been following this discussion: this will
allow the use of MS-DOS Kermit 3.14 via the IBM TCP/IP COMTCP Int 14
redirector, by telling MS-DOS Kermit to "set port bios1". Another method,
which already worked, was to use SIO.SYS, VSIO.SYS, VX00.SYS, and
VMODEM.EXE (all from Ray Gwinn, shareware), and then use MS-DOS Kermit
3.14's "set port fossil 1" communication path. The latter method results
in much better performance. A third method would have been to install a
second Ethernet board and use it in the normal DOS way (e.g. with a packet
driver) in a DOS window.
The reason for wanting to use MS-DOS Kermit, rather than OS/2 C-Kermit, to
make TCP/IP connections from Warp is for MS-DOS Kermit's Tektronix 4014
graphics terminal emulation, a feature that OS/2 C-Kermit does not yet
have.
Note that MS-DOS Kermit's graphics terminal emulation works only in a full
screen session, not in a window.
