I would suggest that you or anyone else use 7 data bits, EVEN parity, 1 stop bit, and the highest baud rate that works reliably. However, you must use 8 data bits for XMODEM mode.

7 data bits vs 8 gives you about 10% greater thruput. EVEN parity catches many noise errors, but there is no correction, HAAS just aborts. 1 stop bit vs 2 is about 10% greater thruput. Admittedly EVEN or ODD parity vs NONE costs 10% in thruput, but the increased value of detecting many errors is worth the loss in thruput.

If you want high baud rate, long cable length, and electrical isolation simultaneously see our I232 System at www.beta-a2.com .
