grabserial - Serial line reader
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.
grabserial [options] <config_file>
-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
grabserial -e 30 -t -m ^Linux version.* This will grab serial input for 30 seconds, displaying the time for each line, and re-setting the base time when the line starting with "Linux version" is seen.
