My boss recently bought PC-NET from Santa Clara Systems. It looked
great -- it would let us run off our XT from the next lab, sharing the
hard disk, etc. However, when we installed the card that ran the
software, we found that our modem, plotter, and, in fact, everything
we ran off our COM2: port (we have a box that lets us run 4 things
out of one async port) was confused -- the stuff we sent out the port
was fine, but what we received was absolute garbage !!!
I had been away for a week or so, so I thought that perhaps the users (!)
had somehow trashed the system. However, I eventually read the PC-Net
documentation and found out that ther are two (2) ways that you can
configure their board:
1) Use hardware interrupts 2 & 5
2) Use interrupts 2 & 3
So I checked the Technical Reference Manual and lo and behold:
1) Interrupt 5 is the Fixed disk interrupt (don't want to mess with that!)
2) Interrupt 3 in the Asynchronous Communications interrupt (secondary)
(can't mess with that either !)
So what's a girl to do but send the !%#@^*# thing back
(Fortunately we hadn't actually paid for it yet :-) )
