View Full Version : /dev/ttyS0 I/O error

10th June 2005, 04:16 PM

I have a laptop running FC3 which I am trying to use to comunicate with some hardware through the serial port. If I execute 'tty -a -F /dev/ttyS0' I get 'input/output error'. I
executed the 'setserial' command on this device, and confirm that this is tied to COM1. So
I assume that I am trying to talk to the correct port.

Any thoughts as to why the I/O error is occuring? It happens even if I am root.

Thanks in advance.
