* Support traditional hex output format such as:
00000000 74 65 73 74 20 74 65 73 74 20 74 65 73 74 20 74 |test test test t|
00000010 65 73 74 64 66 0a 61 0a 66 61 0a 66 0a 61 73 66 |estdf.a.fa.f.asf|
00000020 64 61 64 73 66 61 73 66 64 61 73 64 66 61 64 73 |dadsfasfdasdfads|
00000030 66 0a 61 73 64 66 61 64 73 66 61 73 64 66 61 73 |f.asdfadsfasdfas|

* Add support for activity based time stamping in normal output mode
Already supported in hex output mode.
* Advanced line mode
Current line mode only support backspace editing. Would be nice with arrow
key navigation left/right and insert/overwrite support. Also history browsing
pressing up/down.
* Allow tio to connect to socket
After some more consideration I think it makes sense to support connecting to a
socket as that will make tio be able to both serve a serial port via a socket
and connect to it - it will be an end to end solution. In short we will be able
to do the following:
Host serial port on socket (existing feature):
$ tio --socket unix:/tmp/tio-socket-0 /dev/ttyUSB0
Connect to same socket (new feature):
$ tio unix:/tmp/tio-socket-0
Besides a bit of refactoring the following required changes spring to mind:
* Socket mode and type of socket should be activated via device name prefix. For example:
* UNIX socket: tio unix:<filename>
* TCPv4 socket: tio inet:<ip>:<port>
* TCPv6 socket: tio inet6:<ip>:<port>
* If no port number defined default to 3333
* Mapping flags INLCR, IGNCR, ICRNL needs implementation for socket mode
* Error messages should just say "device" instead of "tty device" etc.
* Remove other tty'isms (tty_write() should be device_write() etc.)
* In session key commands that do not work in socket mode should either not be listed or print an error messages if used.
* All non-tty features should continue work (auto-connect etc.)
* Shell completion script update
* Man page update
* Split I/O feature
Allow to split input and output so that it is possible to manage these
independently.
The general idea is to redirect the output stream on the socket port number
specified but then redirect the input stream on the same port number + 1.
Example:
$ tio /dev/ttyUSB0 --socket inet:4444,split-io
Will result in output stream being hosted on port 4444 and input stream
hosted on port 4445.
For file sockets something similar can be arranged:
$ tio /dev/ttyUSB0 --socket unix:/tmp/tio-socket-0,split-io
Will result in output stream being hosted via /tmp/tio-socket-0 and input
stream hosted via /tmp/tio-socket-0_input
* Websocket support
Extend the socket feature to redirect serial I/O to websocket on e.g. port
1234 like so:
$ tio --socket ws:1234
Use libwesockets to implement feature.
