Just fine so long as you're using Synchronet for Windows. It has a built-in virtual UART and FOSSIL driver on Windows, for just this purpose. And on Linux, sysops use DOSEMU for this purpose.

Not for a 16-bit DOS program.

Perhaps, but I don't think you'll find a curses implementation for TP.

Try a bunch of them. OpenDoors is probably the best one for C/C++. For Pascal, I think there are a ton of options (door devkits), but 16-bit DOS or native (32-bit) is the first big fork in the road for you to decide.
