This change reintroduces timestamping in hex output mode but based on
timeout instead of new lines which made no sense. This means that
timestamps will only be printed when timeout time has elapsed with no
output activity from serial device.
Adds option --timestamp-timeout <ms> for setting the timeout value in
milliseconds.
Defaults to 200 ms.
Remove options and rework input handling so it is possible to do the
same thing but via script which is much more flexible.
These options were always a bit of a hardcoded solution. With the new
script expect feature we can wait for any type of response.
For example, pipe command to serial device and wait for line response within 1 second:
$ echo "*IDN?" | tio /dev/ttyACM0 --script "expect('\r\n', 1000)" --mute
Add simple expect functionality.
The expect(string) function will wait for input from the tty device and
only return when there is a string match. Regular expressions are
supported.
Example:
script = expect('password:'); send('my_password\n')
Replaces -x, --hexadecimal option with --intput-mode and --output-mode
so it is possible to select hex or normal mode for both input and output
independently.
To obtain same behaviour as -x, --hexadecimal use the following
configuration:
input-mode = hex
output-mode = hex
On some platforms calling high()/low() to switch line states result in
costly system calls whick makes it impossible to swith two or more tty
lines simultaneously.
To help solve this timing issue we introduce a tty line state
configuration API which can be used instead of using
high()/low().
Using config_low(line) and config_high(line) one can set up a new line
state configuration for multiple lines and then use config_apply() to
finally apply the configuration. This will result in only one system
call to instruct the serial port drive to switch all the configured line
states which should help ensure that the lines are switched
simultaneously.
Example:
script = config_high(DTR); config_low(RTS); config_apply()
Add ONULBRK mapping to map nul (zero) to send break signal on output.
This is useful if one needs to e.g. send the break signal to the tty
device when connected via socket.
Add support for running Lua scripts that can manipulate the tty control
lines. Script is activated automatically on connect or manually via in
session key command.
The Lua scripting feature opens up for many posibilities in the future
such as adding expect like functionality to easily and programatically
interact with the connected device.
When entering a file name, eg. 'test' it whould output the following
with 2 stale letters of the former input string:
[14:41:58.987] Send file with XMODEM
[14:42:08.015] Sending file 'test'st
[14:42:08.015] Press any key to abort transfer
To avoid this we simply overwrite the 2 stale letters with whitespaces.
