the pc is actually sending data since i am sending and recieveing data from a
stepper motor controller so am sure both cable and pc are sending data
and i looked at the schematic , the pins are correct

i forgot to mention i am running a debian on a cf card that i ordered with the
board
is there anything else to do ?
any suggestions ?
DID anyone ever encounter this problem anywhere ? being able to send and not
receive on a 4wire 485 ?
do you think i should call embedded systems ?
