[TRLog] Serial Card Multi I/O MULTI IRQ

[Thomas M. Schaefer]

The question is...Since TR can access cards by the I/O address, can a card
be put in a system without assigning it an interrupt? I have a system that
is basically full. If I could not use an IRQ, I wonder if it would work.
This is, of course, in DOS and only because TR can access ports by address
as it does not care about IRQ.
