[GreenKeys] ASR33 to Raspberry Pi?

[John]

This actually refers to GrayKeys, but still on-topic:

I'd like to make my 33 be the console for a Raspberry Pi -

I have a Deramp I/O card installed on the 33 and working well - so I'm 
at RS-232 levels.

I can open a terminal window on the RPi.

Looking for a simple set of Unix command(s) to 'redirect' the console to 
the 33 - and later back again.


I'm mostly a hardware guy, and analog at that, so my usual experience 
with Unix/Linux is: "painfully - slowly - copy a command 
letter-by-letter, checking for errors and typos, then hit return."

80% of the time this results in three or four full close-spaced pages of 
error messages and warnings zipping by at high speed - and then the 
system pukes and dies.

I will also confess I don't much "get" GitHub, tho I've watched various 
tutorials and guides - it remains inscrutable. "Not Able to be Scruted". 
I just don't scrute GitHub.

Thanks all!


Cheers
