Becouse you use max its not inverted signal.
on 2400 and true settings should be 396 if you use 4mhz crystal.
here example of code how to star communication with modem if max232 is used:
Code:
 Init:
serout tx,0,["AT",13]
serin2 rx,396,1000,init,[WAIT("OK")]
Tried you way as well. I am using internal oscillator and I put it to 4MHz this time. After that I tried your instructions above but results are the same. Two questions I want to ask you
First: Why have you used "0" in the instruction serout tx,0,...
Second: why have you not used serout2 and used just serout & serin2 instead of serin?
