I wrote an SDLC emulator for a multiplexor board I inherited.
Not a tough job considering I work for the company
that brought you IRMA!

The problem is the serializer on the board only handles NRZ.
It can't hear NRZI.

Seems like there ought to be an attachment for a line that
will sync off the clock and convert the data signal from 
NRZ to NRZI and vice-versa, but I can't find it.  Any help?

Thanks.--
