Watch the little transmitter taped to your NTL box and see if you can
see the little red light blink.

If you invoke the red_eye command directly you can see what it's sending
to the device ... and then you can type those characters to it yourself
if you want.

I have mythtv configured with

        * mythtvsetup -> Input Connections -> S-Video0 (NTL Digital Dublin),
        set "External cahnnel change command" to
"/usr/local/bin/red_eye.script".

so it's invoking a script which has

-- cut --
#!/bin/sh

#debug:
#echo "$*" > /tmp/re.$$

/usr/local/bin/red_eye /dev/ttyS0 $* 2 &
#/usr/local/bin/red_eye /dev/ttyS0 $* 1 &

exit 0
# The exit 0 is important, otherwise mythtv thinks it failed and
# tries to switch back to the previous channel.
-- cut --

I've tried having it wait only 1 second, but that always seems to be a
crap shoot on whether all the characters will get sent before it finishes.

Hope this helps,
B
