Serial port naming conventions
By default, each port is associated with three entries under the /dev directory.
Two take the form /dev/comfxy and /dev/term/comfxy where x is the card number (1-4) and y
is a lower case letter in the range a-p. a is port 1, ..., p is port 16. These device names are
intended for local devices.
The third device name takes the form /dev/cua/comfxy where x is the card number and y is a
lower case letter in the range a-p, as before. These devices are intended for use with
modems.
These mappings can be altered by careful modification of the mkdev and startcomf scripts
in /usr/lib/comf/i86.
