ok i have a dlr -3p cable which has a rs-232 db-9 female connector
it works well on hyperterminal
now the db-9 connecotor i have taken two wires from the rx and tx of the 8051 thru the max 232 and then in the tx and rx of the db-9 (of the dlr-3p)
it should work but when i connect the gnd to pin 5 of the db-9 the controller starts to funtion abnormally plz if anyone has interfaced the 8051 with dlr-3p-- nokia 6310 send me the diagram ,i am sure the programming is not the problem the problem is which of the pins of the db-9 is to be connected to what , thats what i cant figure out , i am sure it has also something to do with rts right? plz answer
