thanks everyone but i am starting to think its not my code that's wrong it's
just the cable connections
i am configuring with my code port COM2 to 485 FULL DUPLEX
but i am using a null modem cable THE SAME I USED TO TEST ports 232 and
connecting that modem cable to a converter cable from 485 -> 232 then reading
with minicom Through a 232 TO USB
I think that sending from 485 port to a null modem( that was used with success
with 232 ) is the mistake
ANYONE KNOW IF I should get A 485 null modem cable ?
IS THERE ANY DIFFRENCE between NULL MODEM CABLES ? SOME FOR 232 QND OTHES FOR
485 FULL DUPLEX ?
