Hello Yesuraj,

I used pyserial several times with one-chips to do some lower-level stuff but for regular machines (like setting boot device in bios boot menu or some things on the forth interpreter on s390) I'm using aexpect.ShellSession with conserver-client which allows me to read_until_pattern_matches, read_nonblocking, send/sendline/sendcontrol or cmd on booted system, which is usually all I need. Note you can replace the conserver-client with socat or other terminal program.

If you chose to go into aexpect way, you can always share your helper functions with upstream.

Regards,
Lukáš
