Using RS232 Interface / disable system output (12.04)

Postby kruszi » Wed Jan 25, 2017 5:02 pm

Hi,

is there any way to disable the output / input from the system on the RS232 while maintaining bootmessages? Currently there is console output (and input possible) on there. Ubuntu 12.04.

dmesg reports:

Code: Select all
console [ttymxc0] enabled, bootconsle disabled


Any chance to have a "pure" RS232 Interface to connect another device to ?
