FreeBSD byzantine 3.2-STABLE FreeBSD 3.2-STABLE #5: Sat Aug 7 23:43:54 GMT 1999 root@byzantine:/usr/src/sys/compile/BYZANTINE i386
>Description:
Often when I am logged in via telnet to a FreeBSD host, I use Lynx to
download files. If it is a large download, the arrival of talk
requests or write messages can mess up the display of Lynx's status.
This patch to mesg(1) will allow you to use "mesg -t tty" report or
change the status of tty instead of the current. I do this often
from a second telnet session.
>How-To-Repeat:
Irrelevant.
>Fix:
