This timestamp format will print the seconds since epoch along with
subdivision in microseconds.
Example:
[1748009585.087083] tio v3.9-8-g2fb788f-dirty
[1748009585.087156] Press ctrl-t q to quit
[1748009585.087683] Connected to /dev/ttyUSB0
+ Add missing timestamp-format epoch
+ Update send_ to use fsync and tcdrain like normal tty_sync does
+ Rework read_line to save partial line at timeout
+ Simplified read_line to reduce cyclomatic complexity
+ renamed example files read.lua and read_line.lua
+ moved #define READ_LINE_SIZE to top of file
+ renamed g_linebuf to linebuf, and moved it into read_line as a static variable
To include the contents of another configuration file simply do e.g.:
[include raspberrypi.conf]
Also, included file can include other files which can include other
files etc.
This feature is useful for managing many configuration files and sharing
configuration files with others.
After including the use of glib we might as well replace inih
with the glib key file parser.
All configuraiton file parsing has been reworked and also the options
parsing has been cleaned up, resulting in better and stricter
configuration file and option value checks.
Compared to old, configuration files now requires any default
configurations to be put in a group/section named [default].
Configuration file keywords such as "enable", "disable", "on",
"off", "yes", "no", "0", "1" have been retired. Now only "true" and
"false" apply to boolean configuration options. This is done to simplify
things and avoid any confusion.
The pattern option feature has been reworked so now the user can now
access the full match string and any matching subexpression using the
%mN syntax.
For example:
[usb devices]
pattern = usb([0-9]*)
device = /dev/ttyUSB%m1
Then when using tio:
$ tio usb12
%m0 = 'usb12' // Full match string
%m1 = 12 // First match subexpression
Which results in device = /dev/ttyUSB12
* Rename --list-devices to --list
* Rename --no-autoconnect to --no-reconnect
* Switch -l and -L options
* -l now lists available serial devices
* -L enables log to file
* Add option --auto-connect <strategy>
* Supported strategies:
* "new" - Waits to connect first new appearing serial device
* "latest" - Connects to latest registered serial device
* "direct" - Connect directly to specified serial device (default)
* Add options to exclude serial devices from auto connect strategy by
pattern
* Supported exclude options:
* --exclude-devices <pattern>
Example: '--exclude-devices "/dev/ttyUSB2,/dev/ttyS?"'
* --exclude-drivers <pattern>
Example: '--exclude-drivers "cdc_acm"'
* --exclude-tids <pattern>
Example: '--exclude-tids "yW07,bCC2"'
* Patterns support '*' and '?'
* Connect to same port/device combination via unique topology ID (TID)
* Topology ID is a 4 digit base62 encoded hash of a device topology
string coming from the Linux kernel. This means that whenever you
plug in the same e.g. USB serial port device to the same USB hub
port connected via the exact same hub topology all the way to your
computer, you will get the same unique TID.
* Useful for stable reconnections when serial device has no serial
device by ID
* For now, only tested on Linux.
* Reworked and improved listing of serial devices to show serial devices:
* By device
* Including TID, uptime, driver, and description.
* Sorted by uptime (newest device listed last)
* By unique topology ID
* By ID
* By path
* Add script interface 'list = tty_search()' for searching for serial
devices.
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
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
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.
Add --log-append option which makes tio append to any existing log file.
This also changes the default behaviour of tio from appending to
overwriting any existing log file. Now you have to use this new option
to make tio append.
Accept "true", "enable", "on", "yes", "1" as true values, their
counterparts as false ones. Check integer values for errors and range.
Warn about ignored (e.g. misspelled) options.
Check getenv() return value for NULL.
Rename "tiorc" to "config", as it's a static INI file, not an executable
"run commands".
The feature is detailed via the following option:
--alert none|bell|blink
Set alert action on connect/disconnect.
It will sound the bell once or blink once on successful connect.
Likewise it will sound the bell twice or blink twice on disconnect.
Default value is "none" for no alert.
Many modern RS-485 serial devices such as the ones from FTDI already
operate in RS-485 mode by default and will work with tio out of the box.
However, there are some RS-232/485 devices which need to be switched
from e.g. RS-232 to RS-485 mode to operate accordingly on the physical
level.
This commit implements the switching mechanism and interface required to
enable RS-485 mode. It only works on Linux and with serial devices which
use device drivers that support the Linux RS-485 control interface.
The RS-485 feature is detailed via the following options:
--rs-485 Enable RS-485 mode
--rs-485-config <config> Set RS-485 configuration
Set the RS-485 configuration using the following key or key value pair
format in the configuration field:
RTS_ON_SEND=value Set logical level (0 or 1) for RTS pin when sending
RTS_AFTER_SEND=value Set logical level (0 or 1) for RTS pin after sending
RTS_DELAY_BEFORE_SEND=value Set RTS delay (ms) before sending
RTS_DELAY_AFTER_SEND=value Set RTS delay (ms) after sending
RX_DURING_TX Receive data even while sending data
If defining more than one key or key value pair, they must be comma
separated.
Example use:
$ tio /dev/ttyUSB0 --rs-485 --rs-r485-config=RTS_DELAY_AFTER_SEND=50,RX_DURING_TX
Add a simple line response feature to make it possible to send e.g. a
command string to your serial device and easily receive and parse a line
response.
This is a convenience feature for simple request/response interaction
based on lines. For more advanced interaction the socket feature should
be used instead.
The line response feature is detailed via the following options:
-r, --response-wait
Wait for line response then quit. A line is considered any string ending
with either CR or NL character. If no line is received tio will quit
after response timeout.
Any tio text is automatically muted when piping a string to tio while in
response mode to make it easy to parse the response.
--response-timeout <ms>
Set timeout [ms] of line response (default: 100).
Example:
Sending a string (SCPI command) to a test instrument (Korad PSU) and
print line response:
$ echo "*IDN?" | tio /dev/ttyACM0 --response-wait
KORAD KD3305P V4.2 SN:32477045
Replace existing toggle and pulse key commands with the following
generalized key commands which allows to toggle or pulse all serial port
lines:
ctrl-t g Toggle serial port line
ctrl-t p Pulse serial port line
When used, user will be asked which serial line to toggle or pulse.
Also introduce --line-pulse-duration option for setting specific pulse
duration in milliseconds for each serial line using a key value pair
format. Each key represents a serial line. The following keys are
available: DTR, RTS, CTS, DSR, DCD, RI.
Example:
$ tio /dev/ttyUSB0 --line-pulse-duration DTR=200,RTS=300,RI=50
Likewise, the pulse duration can also be set via configuration file
using the line-pulse-duration variable:
line-pulse-duration = DTR=200,RTS=300,RI=50
Introduce "bold" color option which only apply bold color formatting to
existing system color.
Also make "bold" the default color option.
Fixes all white issue with black on white tio text.
Make it possible to remap the prefix key (default: ctrl-t) by setting
the prefix-ctrl-key variable in the configuration file.
Allowed values are in the range a..z.
Example, to set the prefix key to ctrl-a simply do:
prefix-ctrl-key = a
Clean up so that only the following error related printing functions are
used: tio_error_printf(), tio_error_printf_silent(),
tio_warning_printf().
A session mode switch is introduced for error printing so that it will
print error messages with better formatting depending on in or out of
session.
