Description [edit section]

If the combination of command and prompt are too long, then sersh does not work properly with 'busybox sh' on the target.

On the target (after installing busybox):

$ /bin/busybox sh
$ export PS1="root@beaglebone:busybox_sh_long_prompt $ "

Then on the host:

$ serio-test.sh ttyACM1

And I got the error message:

Doing cleanup
'
ERROR: invalid literal for int() with base 10: '[ [&&serio_cmd_done&&]]'

Notes [edit section]

Note that there's a warning comment about this in the serio program source.

It appears to be something related to busybox echoing a line feed or carriage return in the middle of the response from the command that is executed by sersh.

I think someone got this working with some stty adjustments or some settings changes to busybox (I can't remember the details). Check for messages relateing to busybox on the mailing list in Spring of 2017.
