But, and it's a BIG but, the abbreviation for megabaud is MBd, not Mbd, even though 'baud' is written without a capital B if spelled out in full either singularly or with a prefix, e.g. baud, kilobaud, megabaud etc so a bit of a trap there too.
Be careful with the next post or you'll be on doggy-doo duty.
I'm really hoping G will weigh in with something i can tear apart now though ......
