Not at the first char I send but when I send 4 or 5 times a char A (example) then I recieve something. Not always the same and not what I would expect. Seem something is out of sinc. I already doble cheked the baud rate but everything is fine. I now aded a sirout command for trying the other way and that is without any problem running fine (serout rc.3,T9600,"Q") I recieve in hyperterm always that what I send. I never tried without a max233. I always use that as buffer. So I realy like to keep him between. I had some problems on javeline stams if It was not used so now I 'm always putting him between. If you want I can make a temporary bypase for testing but eventualy I like to have him up and running with the max233. I thout it was no issue for using it. So sending is no problem but recieving gives me data but strange. stef ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=193796#m193811 Need assistance?
