RS232

Hello,

I've got a problem with the acquisition of values in the RS232 port.
I send binary values to it and I received nothing.
The message error is I/O operation timed out.
I don't understabd where does it come from. If someone know the answer, thanks.
Best regards
Olivier

Your details are a little sketchy but here is some info.
It sounds like the reason you get the time out is because the device
connected to the serial port is not sending any data. Since nothing arrives
in the alloted time the port times out.

Check that the communication (buad, # of bits , etc) with the device is right.
Check that the data you are sending is right.
Check that you have properly requested that the device return data.

If the device takes a LONG tim
e to respond you may need to increase the timeout
value.
