Your diseqc addition introduces a new bug.

The problem occurs because you have a lookup table with fixed
command lengths and the diseqc command is:

1. omitted from the table, so is assumed to be an invalid command.
2. has a variable length so can't be added to that table.

there are two solutions, either hack it to work OR remove the table
and put the lengths in the calling functions.

in order to test diseqc i will do (2) above and determine if
it works.
