These two programs allow for quick configuration of the serial
modem port and serial printer ports on Kaypros.

Usage:

SETMDM  Speed,BPC,Parity,STB     ...for the modem port
SETPRN  Speed,BPC,Parity,STB     ...for the printer port

Where:
         Speed is the baud rate.  (from 50 to 19200)
         BPC is the number of bits per character  (5,6,7, or 8)
         Parity is 'E' (even)
                   'O' (odd)
                   'N' (none)
         STB the number of stop bits (1 or 2)

Example:
        To set the modem port with baud rate 1200, 8 bits per character,
        no parity, and 1 stop bit, say:
        SETMDM 1200,8,N,1

        To leave a parameter unchanged, say:
        SETMDM   1200,,N,1    (leaves bits per character unchanged )

        Note:  You cannot change parity and stop bits independently of
        each other, since they occupy the same write-only register in the
        SIO chip.  Therefore, if unspecified, Parity is None and Stop bits
        is one.  However, if both are unspecified, they are not changed.

        Also, due to constraints in programming the SIO registers, the
        following configuration is used in the SIO.

           If bits per character are specified, then:
              - Receive is enabled; Transmit is enabled;
                DTR and RTS set active; "Auto Enables" is disabled.
           If parity or stop bits is specified then:
             - X16 clock mode is used (This is mandatory anyway).
