COM3/4 driver needed for PC6300+

[news]

I have a PC6300 Plus (AT&T 5.2 Unix)
that comes standard with the COM1 (tty1) serial
driver and also have the tty2 add-on driver. I'd like to know if anyone
has hacked the tty2 driver for tty3 and tty4. Or if anyone could tell
me how to approach the problem.

All advice is appreciated.

Thanks,
Mike Anderson
