1 | "neocon" is a simple serial console utility that tries to open a |
2 | ttys that may exist on a system until one such open succeeds. It |
3 | then passes terminal input and output, until there is a read or |
4 | write failure on the tty, in which case it disconnects, and the |
5 | process restarts. |
6 | |
7 | This is mainly intended for serial over USB interfaces that |
8 | disappear when the Neo or debug board is restarted. E.g., |
9 | neocon /dev/ttyUSB0 /dev/ttyUSB1 |
10 | |
11 | The option -t delay_ms throttles keyboard input to a rate of |
12 | one character every "delay_ms" milliseconds. This can be used to |
13 | prevent buffer overruns on the remote end. |
14 | |
15 | "neocon" can log to a file with the option "-l logfile". Non-ASCII |
16 | and non-printable characters are converted to hash signs (#). To |
17 | append to an existing logfile, add the option "-a". To add a |
18 | timestamp before each line, use the option "-T". |
19 | |
20 | To leave neocon, type "~.". The escape character (~) can be changed |
21 | with the option "-e escape". |
22 | |
23 | To manually switch to the next device, enter "~n". |
24 | |
25 | The option -L switches console input from character-by-character |
26 | (raw) mode to local line editing (cooked). Edited lines are sent |
27 | with \n termination. |
