Yes it is, and it can take a bit of fiddling to get that to work
reliably. I had to do the same (i.e. use raw mode), and it's taken me
many months of tweaking to get right.

I've only ever done this once (i.e. with my STB which is not a Cisco),
but the two things I've done that made the most difference to
reliability were:

- keep it as simple as possible. Include only one iteration of the raw
codes in your config file.

- use a reasonable interdigit time. Pick something that is close to what
a human could achieve when using the remote, but not too long so as to
avoid that the STB thinks you're done sending digits. I've set mine to
350ms:

LircChannelChanger --remote=digibox --transmitter=1 --delay=0.350
--digitprefix=Num $1
