I've had no luck trying to access the serial port which comes up as /dev/ttyS0.
Code: Select all
$ dmesg | grep serial
[ 0.660044] serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
Code: Select all
sudo apt-get install minicom
I've tested the source of the serial signal I'm trying to read via a USB-to-RS232 coverter from FTDI:(http://www.ftdichip.com/Support/Documen ... -PLUS4.pdf)
The signal comes in just fine (over /dev/ttyUSB3) once I set the serial port options (via setserial and stty). However, if I plug in the serial port using the supplied cable and perform the same settings with /dev/ttyS0, there is nothing.
Is there anything I can do to test the cable or fitpc?
Thanks,
Dean
