gpscat 1 16 Nov 2006 gpscat dump the output from a GPS gpscat -s speed serial-port gpscat is a very simple little program that reads from a specified serial device (presumed to have a GPS attached) and dumps the output to standard output. Nonprintable characters are rendered as hexadecimal string escapes, except for CR followed by LF or LF preceded by CR. The program runs forever until interrupted by ^C or other means. This program is useful as a sanity checker when examining a new device. It can be used as a primitive NMEA logger, but beware that (a) interrupting it likely to cut off output in mid-sentence, and (b) to avoid displaying incomplete NMEA sentences right up next to shell prompts that often contain a $, it always emits an extra final linefeed. The program accepts the following options: -s Set the port's baud rate (and optionally its parity ad stop bits) before reading. Argument should begin with one of the normal integer baud rates (300, 1200, 4800, 9600, 19200, 38400, etc.). It may be followed by an optional suffix [NOE][12] to set parity (None, Even, Odd) and stop bits (1 or 2). -h Display program usage and exit. -V Display program version and exit. Specifying -s 4800N1 is frequently helpful with unknown devices. gpsd8, gps1, libgps3, libgpsd3, gpsfake1. gpsprof1, gpsctl1, sirfmon1. Eric S. Raymond esr@thyrsus.com.
