Yes, but you need to know the name of the device driver, and this is
usually pretty difficult to find. Serial ports use two separate drivers -
one for input and one for output. Usually the names are something like
this: ".xxxIn" and ".xxxOut" where xxx is the port name. As long as the
port's dirvers are named this way you can use "-Sxxx" to set the serial
port name to xxx. If the driver names don't match this pattern, you need
"-Sxxx:yyy" where xxx is the full name (including the '.') for the input
driver, and yyy is the full name of the output driver.
I'll e-mail you a little program that lists the serial port driver names.
MacNQC, which is currently in development, should make this a lot easier.
It provides a graphical front end to NQC including a nice popup menu for
serial port selection.
