This program was written in 1990 in Fortran for the classic Amiga.  It continues
to work on my uA1c under OS4.0 and above.  It supports the A2232 multiport
serial port card for the classic Amiga (that is, it can use serial ports 0
through 7).  It sends commands over the serial port to an X10 CP290 home control
interface which in turn sends commands over the household wiring to X10 modules
which can turn devices off and on.
