I understand that there are multi-port serial boards out there.
I also understand that the device-level interfaces are essentially
the same as serial.device (mod Open parameters).  My question is this:
Do the current boards support 'AUX:' style devices?  That is,
can I Open("AUX:1", MODE_???) and Open("AUX:2", MODE_???) and
read/write these (in a blocking way, of course)?  (Or whatever the
device names may be.)

On a related question: When a user types a control-C, control-D,
control-E or control-F on the AUX: connection, does the device-reader
get Signal bits set?  If so, exactly how does the device driver
determine which task gets its bit(s) set?  Also, how does
CON: determine which Task gets the bits set?  

(This is for a BBS, in case you wonder)
