-----------
There's still room to slip between the cracks here. MS-DOS Kermit
has built-in Telnet over its own TCP/IP stack. But it does not pretend
to be a console interpretor for DOS (command.com does that). Even DOS
itself is largely unable to do that task with its CTTY command.
What you apparently need is a screen grabber/repeater and a
keyboard grabber/stuffer for the other direction, a la PCAnywhere. This
becomes particularly true if the application bypasses DOS itself for
video or keyboard (and many do, given what DOS offers). That means the
repeater pair must snoop within video display memory itself, and at the
other end the client side needs to grab keypress primatives within the
Bios or lower and stuff them into the matching keyboard simulator on
the other end. This is not the task Kermits engage in, hence the need
for a PCAnywhere program.
There is an alternative worth looking at, which is the DOS
simulators which run under various versions of Unix. If, and I can't
predict the size of that "if" for your situation, the app were well behaved
enough then the Unix machine could support it and a regular Telnet session
would be what the doctor ordered. SCO Unix and SCO UnixWare, amongst others,
offer decent DOS simulators as options.
