I spent some time playing with #tty last night and I realized what I did wrong last time when I tried to talk to a tty. The response does not have to arrive in one read call.
I also ran into 7bit vs 8 bit encoding difference that my parser did not handle.
What bugs me the most is lack of sensible single place that documents all of the protocols involved. There's a range of odd websites, man pages, PDFs and websites but nothing cohesive.
Please tell me I'm missing a well-know resource.
