ASR 33 Baud and Rate

Didn't we do this a couple of weeks ago? :-) An ASR33 serial 'character' cosnists of 1 start bit (space), 8 data bits, and 2 stop bits (mark). The ASR33 consists of 4 extions : pritner, punch, reader, keyboard. They act as follows. Pritner : Ignores bit 7 (the high bit). Punch : Punches all 8 bits onto the tape, does not check parity. Reader : Reads all 8 bits from teh tape, sends them as they are. Again does not check parity Keyboard. There are 2 versions. One alwayses ssends a Mark parity bit. The other sends even parity. So, I would recomend settign the serial port to 8N2, and masking out the high bit if appropriate. This will allow you to use all 8 tracks on the paper tape. If you have the 'parity' keyboard, you could set 7E2, bt then, of course, thee tape punch will punch even parity characters (since that's what the serial port is sending). -tony
