That is why I've never gotten them to work. Most users will want to have
activity on com1/3 (com2/4) at the same time, resulting in problems. I
therefore limit myself to com1/2 and suggest that to others. PeeCees are
bad enough, with the limited number of interrupts (way too limited), without
adding to the problem by trying to share interrupts. Something will go wrong
sooner or later.
>Oh, and try using /dev/cua[0123] instead of /dev/ttyS[0123].
Correct.
