Hitting return a few times on the terminal will get
the attention of
the
device; e.g. Raspberry Pi, that it's connected to.
Depending on how said device is configured, you will either get a login
prompt (e.g. getty+login) or a shell prompt (e.g. getty+shell).
Then you will tell said device to connect to the RAID array's
telnet/serial gateway. Nominally, this could be as simple as `telnet
<RAID-gateway-IP>`.
At least that's how I would configure things if I wanted to use a
traditional (dumb) terminal to be able to connect to multiple remote
devices. Talk to the serial /server/ and ask it to connect to the
other
device on your behalf.
Grant,
I agree that is exactly the behavior I want. However, none of the devices that have been
suggested seem to do that i.e. connecting a Lantronix UDS1100 to the dumb terminal does
not provide a usable telnet CLIENT interface. The device has been designed to act as a
telnet SERVER to expose the host (i.e. RAID Controller interface) to the outside via the
telnet protocol. Again for most uses this is all you need. You would then use whatever
modern device you have with a telnet client to connect to your device. I am throwing a
monkey wrench in it by trying to use a 1980s dumb terminal as my I/O device. :)
As we discussed any half decent system (a 486, SPARC, etc.) can provide the intelligence
to do this. I was hoping there was a purpose built box that could be used in a turnkey
manner and be hidden away out of sight for my use. Failing that rolling a Pi system w/
serial HAT or a USB to RS232 adapter maybe the cheapest option as you suggested.
