I'm trying to access the serial port ttyS2 that is set in the BIOS as "OS Controlled" without much success. If it's set it to "Always Enabled", I can access the serial port.
This is on the Intermec CV60, and ttyS2 is the touchscreen port.
# setserial /dev/ttyS2 /dev/ttyS2, UART: 16550A, Port: 0x03e8, IRQ: 6
If I set the BIOS to "OS Controlled", I can't access the serial port no matter what parameter I pass to the setserial. The factory default is "OS Controlled", and Window XP can detect and access the port. There will be hundreds of CV60 to get into the BIOS to set it one by one. If there's a way to access the port in linux, it'll be great!
Thanks, Jeff
