Dear Linux folks,
On a lot of devices, like servers, you have more than one serial console, and you do not always know, how they are numbered. Therefore, we start a console on ttyS0 and ttyS1.
In user space, we also would like to write to both consoles to not worry about the numbering. Writing to `/dev/console` only write to the active console.
$ more /proc/consoles # I think tty0 -WU (EC p ) 4:1 ttyS0 -W- (E p a) 4:65 ttyS1 -W- (E p a) 4:65
Does a device exist, or can a device be configured so you can write to all (serial) consoles from user space?
Kind regards,
Paul
