The interface is dictated by the OpenGroup stands [1] [1] https://pubs.opengroup.org/onlinepubs/009695399/functions/fwrite.html So that can not be changed. There must be a root cause related to what you are doing or a bug in the system. Check the configuration (compare it to other telnet board configs). Are you Entering dmesg on both terminals or on one and it is showing up the 2 terminals? David
