It sounds like you have a problem similar to one I'm working on. I'm
trying to connect a telnet session to a program running in DOSEmu that
uses the com port/modem for input/output.
My approach so far (to avoid using null modem cables), is to use pseudo
tty's. They are devices that come in pairs like "/dev/ptypN" and
"/dev/ttypN". Where N is a single hex digit. You should be able to run
agetty on "/dev/ptypN" and tell DosEmu to use "/dev/ttypN" as the com
port (I havn't actually done it this way myself). Make sure you use a
psuedo tty that is not already in use (telnet connections use psedo
tty's).
I have been able to run a program that attaches stdin/stdout to
"/dev/ptyp9" on my system, and told DosEmu to use "/dev/ttyp9" as com 1
(DosEmu has to be started after "/dev/ptyp9" is opened by the other
program). Then I have been able to do things like "copy autoexec.bat
com1" and get the output on the other end. Unfortunately, that's about
all I've gotten it to do.
I'm still experimenting with this myself, so hopefully someone here can
help us both out. Maybe this will give you something to work with at
least.
