I am strong believer in free software.

I do not believe in Santa, ghosts, fairies, goblins, and gods.

comment How to wait for execution of parallelized processes and stitch together the outputs?
If input.tsv is big (1 GB or more) and xyz is fast (10 MB/s or faster), you should look at --pipepart, too. Otherwise GNU Parallel may be the bottleneck.

comment xargs, records, and standard input
I am sorry you feel that way. Stackexchange encourages not to simply give 1 line answers, but more thorough answers. I can see why you would find most of the answer redundant to you, as you apparently know most of this; but since you did not describe your knowledge, it would be equally fair to assume that you had only heard of Parallel, but never actually used it. To avoid answers like this in the future, describe what you already know. In this case you could have written that you had read the man page, watched the intro videos and walked through the tutorial without finding an answer.

comment How to redirect stdout & stdin to telnet?
To me it is still unclear what you want. My guess is: The device uses /dev/ttyO0 as the console, and you want to see the console. Thus you want to redirect all data that goes to /dev/ttyO0 to something you can reach through the network (such as ssh).

I have not tested it, but it looks about right, yes.

comment Representing/quoting NUL on the command line
And can you explain the behaviour of case 4? Why is B printed, when B is not printed in case 2?

comment How to redirect stdout & stdin to telnet?
What I mean is that I have spent a tremendous amount of time trying to get telnet to behave and have failed. netcat on the other hand worked in first try: echo foo | nc server 23
