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.
Add key command 'ctrl-t f' which will toggle log on/off.
If no log filename has been specified via the 'log-filename' option then
tio will automatically generate a new log filename every time the log
feature is toggled on. Meaning, when toggled multiple times, multiple
log files will be generated.
However, if a log filename has been specified, tio will only write and
append to that same file.
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
This reverts commit c3116b2b56.
On second thought, this is less appropriate when using the configuration
file. We may want to define the log filename in config file but not
necessarily enable log feature.
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.
Added command line options:
-O, --eol-delay to have a separate delay for end of line
-U, --upper to enable translation of lower case alpha to upper case
Added ability to set mark parity.
Added ctrl-t U key sequence to allow enable/disable lower case alpha to
upper case during a session.
Updated Man page with command line options, ctrl-t sequences and
configuration file options.
Updated README.md, with above information.
MCUs like the ESP32 can be reset if the serial port DTR line is
pulsed for a short time. You could just type CTRL-t d CTRL-t d
but that's a little awkward since you have to lift your finger
off the CTRL key to type the Ds. Now you can just type CTRL-T D.
* Added new command "D" to pulse the DTR line. I.E. Toggle its
state twice with a configurable duration between toggles.
* Added new config/command line option "--dtr-pulse-duration"
to set the duration between the DTR state toggles. The default
is 100ms.
When enabled this option will timestamp new lines with the time elapsed
since the line before.
This is a very useful feature to identify which events takes the most
time.
