grabserial
==========
Grabserial - python-based serial dump and timing program - good for
embedded Linux development
See http://elinux.org/Grabserial for documentation and examples.
For help with command line options, use: grabserial -h
Installation
------------
If you have the python 'serial' module, you can just place grabserial
in a directory on your path, or add the directory containing grabserial
to your path, or just invoke grabserial directly.
This should work:
$ sudo cp grabserial /usr/local/bin
$ grabserial
You can also install this as a python module with: 'python setup.py install'
(Some users have reported problems with this - let me know if it doesn't
work for you.)
Examples
--------
$ grabserial -d /dev/ttyUSB0 -e 30 -t -m "^Linux version.*"
Grab serial input for 30 seconds (-e 30), displaying the time for each
line (-t), and re-setting the base time when the line starting with
"Linux version" is seen.
$ grabserial -d COM4 -T -b 115200 -e 3600 -Q -o "%" -a
Log serial data from COM4, with system timestamp (-T)
with settings 115200:8N1:xonxoff=0:rtscts=0 (-b 115200)
to the output file "2017-06-13T22:45:08" (-o "%"), for 1 hour (-e 3600)
and then restart (-a) to create new log.
$ 'grabserial -d /dev/ttyUSB2 -C -q "nsh>" -c free
Send the 'free' command to the serial port (-c free), and show output
until a prompt of "nsh>" is seen (-q "nsh>"). Suppress the command echo
and shell prompt (-C).
Notice - New Default ‘-o’ Behavior
----------------------------------
Using the '-o' option, as in the second example above, with a generic '%'
or a specific pattern that includes a '%d' (date) reference will now close
the output file and open a new one if the system date changes while the
program is running.
If the command from the second example above is started at 11:30pm (system
time), the program will capture data for one hour but **will produce two
output files**; one with the date and time it was started and another with
the date and time that the program first outputs data after the system
time passes midnight.
