Experimental Physics and Industrial Control System
If your USB/Serial adapter creates a Termios-style device in /dev then you can treat it just like an ordinary local serial port.
The system creates such /dev entries dynamically when the USB/Serial adapter is detected. On my OS X machine, for example, plugging in an adapter results in
/dev/tty.PL2303-000013FA
being created.
