Grant may be right i.e. there is no device that make a
shell or a
telnet client available to a terminal and I will have to roll my
own.
I somewhat glossed over the /exact/ specifics desired in the first email
because I'm quite confident that any Linux / Unix (like) OS can do
whatever it is you are trying to do with a serial port. The Raspberry
Pi being a quintessential small form factor system. The question
becomes more what specifically do you want to do so as to use that as
information on how to configure the system. There is effectively no
difference between a Raspberry Pi and a generic 486 and a SPARC Station
5. They are all acting as a tiny system to gateway between a serial
port and the network in one way or another.
Re-reading your original post (germane comment copied below for
convenience) it seems like any Linux / Unix (like) OS would do the
following:
1) Provide a shell prompt -- likely without login -- on a serial port
for the physically connected terminal (emulating) device.
2) Issue telnet / rsh / rlogin / ssh / et al. commands to connect as a
client to remote systems across the network. -- Which command is
simply a matter of what /client/ software is installed on the system.
I have absolutely no experience with Raspberry Pi (or
any of these
mini embedded devices).
My personal opinion is that the Raspberry Pi /physical/ aspect of this
is actually a minor part of the puzzle.
Looking around it looks like a box would set me back
about $130 even
if I can get all the parts:
I'm gobsmacked.
I would have assumed that you could get into something sufficient for
your needs for about a third of that (< $50).
Now I am guessing the Pi 4 is overkill for what I need
(text based
shell running telnet or another telnet client). So nay advice and
guidance is appreciated. Thanks.
I strongly believe that any Raspberry Pi, even the 1st generation, can
handle a single serial port at full speed with no problem.
You /can/ do new if you want to deal with stocking issues. Or you can
do used equipment for much less.
To whit, I believe I have an old 1st generation Raspberry Pi that I'm
not using in a case. I paid $10 for it. Add a USB to RS-232 serial
adapter to it, configure some software, and you're off to the races at
serial speeds.
I'd even be willing to help configure the software and ship it to you.
My wife would be happy to have some small amount of equipment leave the
house.
I'd be happy to see the system being used again.
If you're interested, email me directly to discuss the particulars.
Cover costs and effectively buy me a milk shake. ;-)
