Default ASR-33 and 88-2SIO

I always ran mine as 8-N-2 for all operations. ALtair BASIC itself does not care as it strips any incomming parity bit (as does CP/M) by ANDing the incomming data with 7F Hex (177 octal). During the "boot" process the ASR-33 (or in my case the Remex tape reader) sends 8 bit data that is not stripped by the loader programs but simply stored as "Byte" data.

Frank.
