The vendors of serial-port adaptors may not necessarily use the same
driver conventions -- or even the same utilities -- as the conventional
Linux serial driver. Comtrol Rocketports, for instance, recommend the
'setrocket' program rather than 'setserial'.

The various hardware makers are in control of their own drivers, and
most of the continue to make drivers that have non-modem-control ports
(/dev/cur?? for Comtrol, /dev/cuq[1-4][a-d]?? for Equinox, /dev/cuf??
for Computone) as well as their modem-control tty* equivalents.

On a Computone, when configuring HylaFax, /dev/cuf0 works fine for dialout
but /dev/ttyF0 does not. All I am saying is that one cannot expect or
assume that the behavior of third-party serial boards (especially
'intelligent' ones) will exactly copy that of COM1 and COM2.
