Hi
Just some ideas, no solutions!
Programming the comPorts in DOS is a little nightmare.
The routines to handle the com-speed, databit and so
on are not standarized.
Communicting is pretty easy, pricipe:
open com2 in readwrite mode --> handle2
open com3 in readwrite mode --> handle3
doforever
if data on handl2
send it to handle3
if data on handle3
send it to handle2
DOS knows the special files com2: com3:, similar the unix /dev/ttyS0 special
files.
The implementation of this prog depends on the available
language.
I think it is possible to do that, but perhaps it is easier
to run a Native-Adress-Transltion-Prog on you Pentium. I red
that W98 and NT4/2000 has such a software "on board". OK, this
needs two ethernet-cards (often available) from trash or to
run ppp over the serial link, but I never tried this, sorry.
Bye, Gerhard
