There's more about PSK. PM is used in ´sychronous' transmissions, not
'asynchronous'. The latter is the sort that uses start/stop bits and
sends each byte of the transmission as a unit.
'Synchronous' transmissions are the sort that add this extra clock
signal to the standard RS232 connections. It groups characters together
in large blocks of sometimes 2000-4000. There are no spaces between the
characters in a block where there are in asychronous tansmissions. A
control ('SYN') character always precedes the data, which is book-ended
by an 'STX' char in the beginning and an 'ETX' char at the end.
So, I don't think we need to look for the standard 1-7-1-1 (1-8-1-1)
packets.
