You are welcome. You forgot to cc the Help-Bison list; it's important
that other readers get to know the state of a problem.

I've been trying to develop a small software based character UART.
Eight (8) bit characters have one start bit (a zero) one stop
bit (a one) and one odd bit of parity. Idle states are a one,
so getting 100's of ones in a row is acceptable. The
acceptable format is:
Bison is not built for the kind of problem. You might be able to
do it with Flex. For example, you could have a loop scanning for
the first '0', and when it arrives, you set a start condition for
a rule picking down the next ten characters. If there is
something wrong with them, put them back, and rescan; otherwise
output re character.

Thanks. You're absolutely right. The problem was originally well
suited to Bison which eventually distilled down the problem I
presented - I never bothered to reevulate the tool during the
distallation.
