I am posting this for a friend having no access to internet.
I'll decribe his problem :
Situation : You try to write Windows 3.0 applications which
use 4 serial ports on a 386.
Problem : Access to ports works not properly. Various types of
misbehaviour are shown by the system.
So far he has got no idea what is going on. Besides some rumors
that this is a general problem with Windows.
Question : Any similar experience or even poposals to solve the
problem.
Thank for any help.
Volkmar on the behalf of Bernhard

I've been dealing with this problem personally for the past week or so. It seems that Windows doesn't allow interrupt sharing for the COM ports. I needed to use 3 ports and I ended up using a switch-box on COM2 for an external modem and a serial print-sharing device. Just call Microsoft and complain I guess. Microsoft did send me a fax saying that I could rewrite the BIOS code using DOS debug. This is a bit out of my ballpark. Does anyone else have any further suggestions? - steve -- "Laugh and the world laughs with you... | All disclaimers apply... snore and you sleep alone." | except my own, of course. - anonymous fortune cookie thingy | *** Steve J.
