Hi all, I hope this is possible. I have a server, with a network switch attached to the serial port, and I want to rescan the serial port (/dev/tty) to see if it picks it up? I'd prefer not to reboot the server if at all possible. dmesg reports ttyS0 as the active port: [root at zabackup01 ~]# dmesg |grep tty Bootdata ok (command line is ro root=/dev/System/root rhgb quiet xencons=tty6)
