I am trying to get a PC to send a command to an X-10
device. A FireCracker is plugged to one of the serial
ports and there is a nearby RF receiver. This works
fine through the Firecracker Windows based control
progem.

Problem is that I would like to issue the command
automatically. Say, include it in AUTOEXEC.BAT.
Unfortunately, the X-10's program does not lend
itself to automatic invocation.

I looked at the Firecracker documentation. Turns out
the Firecracker is controlled through the RTS and DTR
control lines, meaning that the program writes to the
UART registers. I have no idea how to do this under
Windows.

Has anyone cracked this problem, or knows of someone
that has?
