1"neocon" is a simple serial console utility that tries to open a
2ttys that may exist on a system until one such open succeeds. It
3then passes terminal input and output, until there is a read or
4write failure on the tty, in which case it disconnects, and the
5process restarts.

7This is mainly intended for serial over USB interfaces that
8disappear when the Neo or debug board is restarted. E.g.,
9neocon /dev/ttyUSB0 /dev/ttyUSB1

11The option -t delay_ms throttles keyboard input to a rate of
12one character every "delay_ms" milliseconds. This can be used to
13prevent buffer overruns on the remote end.

15"neocon" can log to a file with the option "-l logfile". Non-ASCII
16and non-printable characters are converted to hash signs (#). To
17append to an existing logfile, add the option "-a". To add a
18timestamp before each line, use the option "-T".

20To leave neocon, type "~.". The escape character (~) can be changed
21with the option "-e escape".

23To manually switch to the next device, enter "~n".
