Has anybody gotten the IBM PC serial IO card to work using interupts ?
I no this is possible because IBM sells software that does it (without
sources. grr). However, I seem to run into a problem that the interupt
service routine never gets called, that is, not until I run another
program, at which point it starts executing grabage (this is because
I never turn things off, but as far as I can tell, they never get turned
on either.)  Im baffled.  Help.  You can look at what im trying to do
in SRI-KL:<BILLW>IBMPC.A86....

Thanks
