* setport : Provides a command line interface for setcom(). This driver allows
*           the use of the defaults provided for in the setcom routines. The
*           syntax is as follows:
*
*               setport channel <baud> <bits> <stop bits> <parity>
*
*           where channel = Interfacer user number or -1 for System Support bd.
*                 baud = Baud rate 300, 1200 ... or 0 for default.
*                 bits = Number of bits per character 5..8 or 0 for default.
*                 stop bits = Number of stop bits 1..2 or 0 for default
*                 parity = Type of parity to use. E,e,O,oN,n or 0 for default.
* Examples:
*               setport 5 1200 8 1 E            All specified
*               setport 5 1200 8 1              Use default parity
*               setport 5 1200 8                Use default parity and stop
*               setport 5 1200                  Use def parity, stop, length
*               setport 5                       Use defaults for everything.
*               setport 5 0 0 0 E               Spec parity all else defaults.
