Under Unixish systems, usually opening the appropriate device under /dev
will give you access to the serial port. Under Linux, for instance, you'd
probably open /dev/ttyS0 (equivalent to COM1: under DOS). Under Solaris,
I believe, it's /dev/cua/a. This is all part of the Unix philosophy
'everything is a file'. If you can read and write to that /dev file, you
should be able to read and write to the serial port.
