Serial port mulfunctioning?
Hi all, I am new on the forum, so greetings to you.
I have installed RedHat Linux 9 on my IBM ThinkPad T23 laptop and am trying to connect to an EVM board with its serial port. I have started with the minicom program and config the settings already. However, I can not get any response from the board which was loaded with OS already. May I ask where to look for the serial port hardware and driver information on the linux system. It would help a bounch. Thanks in advance. (The port functions fine on MS Windows with COM4 setting, I have tried with ttyS0~3 under the /dev directory on Linux system, no success)
