Jim,

Thanks for the work!

I have the same cable box (and provider) as you, DCT 2244, and am using
the python scripts to change channel successfully:
[root at mythtv dct-channel-1.3]# /usr/local/bin/changechannel.bin 40
changing channel to  040
chancode is  c

I just downloaded/compiled your program but it's not happy:

[root at mythtv dct-channel-1.3]# ./channel -p /dev/ttyS0 -vv 40

(ran as root, python script works fine before or after trying your
program, serial port is ttyS0)

Any idea what's up?

Thanks,
