man grabserial (1): Serial line reader

SYNOPSIS

grabserial

DESCRIPTION

Grabserial is a small program which reads a serial port and writes the data to standard output. The main purpose of this tool is to collect messages written to the serial console from a target board running Linux, and save the messages on a host machine.

USAGE

grabserial [options] <config_file>

OPTIONS

-h, --help: Print this message
-d, --device=<devpath>: Set the device to read (default '/dev/ttyS0')
-b, --baudrate=<val>: Set the baudrate (default 115200)
-w, --width=<val>: Set the data bit width (default 8)
-p, --parity=<val>: Set the parity (default N)
-s, --stopbits=<val>: Set the stopbits (default 1)
-x, --xonxoff: Enable software flow control (default off)
-r, --rtscts: Enable RTS/CTS flow control (default off)
-f, --force-reset: Force pyserial to reset device parameters
--endtime=<secs>: End the program after the specified seconds have elapsed.
--command=<cmd>: Send a command to the port before reading
-t, --time: Print time for each line received. The time is
when the first character of each line is
received by grabserial
--systime: Print system time for each line received. The time
is the absolute local time when the first character
of each line is received by grabserial
-m, --match=<pat>: Specify a regular expression pattern to match to
set a base time. Time values for lines after the
line matching the pattern will be relative to
this base time.
-i, --instantpat=<pat>: Specify a regular expression pattern to have its time
reported at end of run. Works mid-line.
-q, --quitpat=<pat>: Specify a regular expression pattern to end the
program. Works mid-line.
-l, --launchtime: Set base time from launch of program.
-o, --output=<name>: Output data to the named file.
-v, --verbose: Show verbose runtime messages
-V, --version: Show version number and exit
