How to implement 8E2 serial protocol?

[Ingvar]

When recieving, do what Dave said, just use 8E1. PBP will see the extra stopbit as a little pause between the characters, no problems atall and nothing you need to worry about.

When sending, you need to add that extra stopbit. You do that by adding a short pause(1/19200=52us) after each character. You can also use character pacing(which does exactly that). The biggest problem with that is that SEROUT2 paces with milliseconds. If you specify 1ms it may take too much time to send the entire message, but it will work. If your messages are short it may not be a problem.

As all of you wrote, I tried using 19200-8-E-1 protocol to connect my weather station (now writing a little program for PC using freepascal...fast and lazy way ;-) ) and it seems to be tolerant to 1 or 2 stop bits, both for tx and rx.
So I'll try with SERIN and SERUOT as soon I'll have some time to spend (this weekend...I hope!). Fortunately I have to send only very small commands to ws ( four bytes or so... with fixed values), so also the "bit bang" idea (very nice!) may be useful...

Again, thanks a lot!
