hello,
I am using DB9 to DB15 serial cable inorder to reader one byte character send from the circuit I have designed, but I cannot read from the serial port why?

Re: unable to recieve data from serial port 80 80

Are you sure your cable is wired correctly? Try plugging a null-modem adapter into one end or the other.

Re: unable to recieve data from serial port 80 80

yes it is wired correctly, I tried it on my freinds computer using DB9 to DB9 serial cable,but when i used BD9 to DB15 I couldn't get a signal

Re: unable to recieve data from serial port 80 80

To validate your wiring, do you have an adpater to convert your cable back to DB9 on the DB15 side to ensure data can flow through?

Re: unable to recieve data from serial port 80 80

no I don't have,but can i change the wiring in the DB9 adapter so that data could be transmitted through the DB15 adapter?If yes please let me know how I must wire the DB9 adapter
