Hello Jasper77,

Did you manage to run this?
I have 4 serial ports connected also to 4 device. All serial ports are working.
So what I did to my minicom config is to save 4 individual config for individual users. Please see config below.
This is what happen, user1 successfully connected to the device using ttyS0 config (command: minicom user1). While the user1 is connected, user2 tried to connect using his config (command: minicom user2).What happen hear is that the minicom stays offline. Also if I've tried the other users. Did you encountered this kind of problem? Should I do something first?

For user1
pr port /dev/ttyS0
pu baudrate 9600

For user2
pr port /dev/ttyS1
pu baudrate 9600

For user3
pr port /dev/ttyS2
pu baudrate 9600

For user4
pr port /dev/ttyS0
pu baudrate 9600

Can anyone also help me with my idea of using minicom to connect to different devices using different minicom config to different physical serial ports in one RHEL server?

Thanks!
