IMHO you are remarkably clueless in what you are 'designing'.

even skipping the hard hardware level (RS232, RS422, RS485),
soft hardware level (baud rate, parity, etc.)

COM as a blocking call is hugely useless.

just imaging calling your "external:eternal-september.org:119" as a blocking call.

forgot to plugin modem line? wait a minute and reboot.
forgot to power up the modem ? wait a minute and reboot.

DNS resolver (eternal-september.org) not online? reboot.

eternal-september.org on maintenance or power failure? reboot.

your C90 everything design is simply not suited to real-world communication.

the socket interface was invented/designed for exactly this purpose.

of course, you may develop a TSR that does all this TCP/IP stuff and looks on top like
fd = fopen("external:eternal-september.org:119", "r+b"),

but 32-bit MSDOS won't help in implementing it.
