The tty dial in/out problem is unrelated to the SCSI / removable
media problem.
The tty problem has been solved more than 25 years ago.
There are two devices /dev/ttya & /dev/cua0
The dialout device cua0 is blocked as long as a dial in is active
and the dial in device is blocked as long as a dial out is active.
This is a simple task compared to what cdrecord does on UNIX.
There are only two programs with completely different tasks
for ttys. There are many different taks related to CD/DVD sersives.
Two? Which two of getty, ppp, slip, uucico/uucp, kermit, X10power, and
nut? Not to mention the getty+ alternatives which include fax and voice
mail. You were right saying the problem was solved, but your count of
applications is low.
NOTE: nut is one of the serial applications which monitor a UPS, there
are others.
If a good solution is available, applications will change to use the
solution.
