Just FWIW, a com port/internet redirector in softare is not unheard of,
there used to be one for Win95, that just gave "OK" responses to AT commands
thrown at it, except for ATDT, for which it took the remaining text as the
FQDN that you wished to connect to. It would the return a CONNECT string
when the telnet connection was established. (Let you use procomm as telnet
client, which was spiffy). More on topic, this could be done in Linux, if
dosemu uses the linux /dev/ttyS0 devices, by creating a device driver (in C)
that functions as the emulator I described above does, and telling dosemu
that that device was a certain com port. You'd of course have to disable
direct port access, methinks.
