Thread: PICList I/O Port addressing lesson #1
face BY : Mark Willis email (remove spam text)

Folks, the PICList has 3 "I/O Ports".  Seems I need to remind some
people how they're used.

* Posting messages to the "PICList Mail Distribution port", at
<.....PICListspamBeGonespamMITVMA.MIT.EDU>, causes that message to be distributed to all
1800+ members of the PICList  (Those who don't have NoMail set),  who
then read your post and make snide comments if you posted to the wrong

* Posting messages to the "PICList Administration Port", at
<.....PICList-RequestspamBeGonespamTakeThisOuTMITVMA.MIT.EDU>, causes that message to be distributed
to all admins of the PICList  {Jory + Myself, right now}, who then read
your post & try to help.

* Posting messages to the "PICList Command Input Port", at
<EraseMELISTSERVspam_OUTspamEraseMEMITVMA.MIT.EDU>, causes that message to be treated as a
command by the listserve software, THIS and ONLY THIS is the address to
send Unsubscribe requests, Set NoMail requests, and so forth.  The
listserve software ONLY listens here for commands, you can send them to
those other "ports" all you want, and all you'll get is a copy back from
the machine, telling you you've made a mistake.

Same as on a PIC chip, using the wrong port for the wrong purpose may
result in unintended consequences, like annoyed list neighbors or
flustrated admins.

The ListServe machine is even simpler than ANY PIC;  It doesn't take all
that much learning to add the capability to handle these 3 I/O ports and
to learn the few commands that the third port takes, especially compared
to the relatively huge complexity that the simplest PIC chip poses by
comparison! <G>
