OT - Very simple serial application

["seniorsimon" <simon.ryley@xxxxxxxxxx>]

Does anyone know of a very simple serial port app that can be called
from the command line and configured using command line arguments.  I
need something really simple to use with my HTPC so I can switch the
input source on my LCD TV using the HTPC remote control.  The LCD TV
has a serial port which offers a variety of useful control options.

What I need is something that can be called thus:

simpleserialapp COM1 9600 8 N 1 I A V D CR

which would tell the app to open COM1 with baudrate 9600, 8 bits, No
parity, 1 stop bit and transmit characters I A V D then carriage
return.  After that close and release the serial port.

I could then call this serial app with a button mapping in the remote
control script file.

Hope that makes sense,  I've tried googling but can't seem to pick the
correct search terms.

TIA,

Simon
