Hi all.
I'm triying to send data and receive data in serial port. I create a shifter-dsmg600.jpg (http://dns323.kood.org/dsmg600/_detail/ … ache=cache) and I conect to con4. After that, I do a Serial Loopback Test with pin# 2 and pin# 3 shorted and write a bash script:
#!/bin/sh exec 3<>/dev/ttyS0 echo "Command 1" >&3 read response <&3 echo "$response" >>/tmp/responselog exec 3>&-
But the script no receive, and wait until break the script.
Help, please....

After to read a lot of this theme ( I'm a newbie to use serial port in linux), I discover that the serial port is configured to console output:
/mnt/HD_a2 # dmesg | grep tty Kernel command line: root=/dev/ram console=ttyS0,115200 :::DB88FXX81:egiga0:none ttyS0 at MMIO 0x0 (irq = 3) is a 16550A
I'm interested to use this serial port as a detector of 0/1 (conect to switch) to control and log. The program in sh it isn't problem, only needs control over the serial port.
