If you're talking about the terminal function in the likes of
Procomm, the OS doesn't even enter into things (unless you're a
complete idiot about things) outside of, say, logging to disk and
keeping dialing directories.
Haven't you ever written any OS-less software for a PC that simply
boots from a floppy? Given that there's a BIOS in ROM, such things
are pretty easy to do if you don't like OS-es. One could easily
write a PC terminal program that didn't use DOS or any other OS for
that matter. For that matter, one could replace the BIOS with a
terminal program and throw away the disks entirely.
