Greetings all; This machine has only one serial port, which I normally use a session of minicom to connect as a terminal quit a bit dumber than a vt102, to a TRS-80 Color Computer 3 in the basement. But my normal config for minicom is /dev/ttyS0, but it claims the device is taken.
Sure enough, an lsof|grep ttyS0 shows an agetty attached to it. And a killall agetty as root only changes its pid until I've done the killall as rapidly as I can uparrow and repeat it 6 or 7 times. grepping thru /etc does not seem to find any hits, so I've no clue whats starting it. So next I will do a search thru synaptic and remove it if it will let me, or somehow disable it forever. And the search for agetty in synaptic is also empty. But as root, a locate agetty hits paydirt. root@coyote:~$ locate agetty /sbin/agetty /usr/share/doc/util-linux/modems-with-agetty.txt /usr/share/man/man8/agetty.8.gz And the man 8 agetty page seems to indicate its a serial connection, I've heard of as being available for troubleshooting even if its not fully booted. Great, except I'm not sure I could go to the coco's keyboard and run supercomm to see into linux, never tried it. In any event, the coco is expecting a cr, and will respond by launching a shell bound to that serial port on its end of the cable. So what I'd like for it to do, is be totally silent during the rest of this machines boot, and once a user, me, is logged in, go away just as silently, freeing the only serial hardware port for my own use. Next problem with minicom running as me is that it has no permissions to save as its .dfl, the options it needs to Just Work as opposed to messing around in its config screens finding a group of setting that will work with the shells available on the coco, which of course is not running its native rsdos, but a unix like system called nitros9 these days. Its os9 plus a few shots of unix testosterone. What do I do next to get rid of this nearly invisible agetty gizmo once this machine is booted? It might be handy if this machine is truly hung, but I can count those instances on one hand with fingers left over in the 21 years I have been a linux only house.
