On my system, I've noticed that DOS applications which try to use
the COM ports will fail if I run them from a DOS subwindow, but
will work properly if I fire them up directly from Windows (via
an icon or by double-clicking on the .exe file in File Manager).

Any idea why? Is there any way to make them work properly when
launched from a DOS subwindow? Thanks.

Do you have any windows apps running that might have taken over control
of the com port in question? Are you using a serial mouse that's
connected to the com port your communications program is using? Check
the type of mouse you are using and its settings.

Try changing the com port settings of the DOS app. You SHOULD be able to
run a DOS comm program Windowed; I did it just last night to connect to a
local BBS with Kermit 3.13.

I t could also be that your DOS app simply refuses to run from a window.
Can you run other DOS apps windowed successfully? If so, then you'll
probably have to run the comm program full screen.

Hope this helps a little.

No.

I think you've misread my post. It's not that I can't run it in a window,
it's that I can't run it when it's launched from a DOS shell window.
I *can* run it when I launch it directly from Windows without using the
DOS shell (e.g. I launch it from File Manager).

Again, that's not the problem. If I launch it from File Manager, I
can run it successfully either as a subwindow or full screen. When I
launch it from a DOS shell window, it won't run successfully either as
a subwindow or full screen.
