I would like for you to explain what this means:

until we uncovered the clients that didn't terminate their last line What?

They closed the socket before sending \r\n?

My code deals with that.

because you're using fixed-length packets, you avoid the actual problem that trapped me
No, not at all.

I thought that I explained clearly how to deal with an indeterminate length \r\n terminated packet.
What was not clear?
Obviously something was not.
It would help if you could ask the question in a different way.

Please look at: sysread. sysread() will return with a number of bytes read.
If the other side sends: "1234\r\n", just look at the end of the buffer to see if there is a line termination (last 2 bytes).
What's the problem?
I think that you can easily adapt my code to deal with your requirements.
