[mythtv-users] Serial DCT Control (dct2224/dct2524)

I've been trying for some time now to get serial channel changing
working, hopefully someone here can provide me with some insight into
the whole problem.

I've got the following:
2x Motorola DCT-2224, firmware version: 7.93
1x Motorola DCT-2524, firmware version: 2.54

I've tried a few different scripts to just try and change the channel
for now, none of which seem to work. When I connect the serial port of a
windows box to these DCTs, hitting enter results in gibberish coming
back from the DCT, followed by the f/w version. I assume this is some
sort of menu prompt (VxWorks?), the reason I assume this is because when
I go through the alphabet on the 2524, different keys produce different
outputs. Seeing as I get gibberish from all three is it safe to assume
that their serial ports are enabled?

When I run the serial cable from the FC4 box to the windows box and run
the python scripts, I do get output over in Hyperterm, so it looks like
I'm sending the data out.

I remember reading in one of the python scripts that it wanted v2.2, but
on my new FC4 box, I have python 2.4 installed, should this be an issue?

I seem to be able to get everything else working except serial channel
changing, so hopefully someone will be able to help me out.
