NAME

       ttycat - Serial Line Output Utility

SYNOPSIS

       ttycat [options] [file] [file] [>stdout]

       ttycat [options] [<stdin] [>stdout]

DESCRIPTION

       Copy  one  or  more  files to a serial device.  This program is similar to traditional cat
       utility but expects stdout to be a serial tty device.  It  will  configure  stdout  before
       writing  and  will  restore the original configuration afterwards.  It can be used to send
       data to the local Atheros UART-enabled powerline device.  If the remote  powerline  device
       is  not  UART-enabled, use program edru to capture and display arriving at the remote host
       and program edsu to send files in the opposite direction.

       This program is part of the Qualcomm Atheros Powerline Toolkit.  See the AMP man page  for
       an overview and installation instructions.

COMMENTS

       This program only supports the Linux and MacOSX  platforms, at present.

OPTIONS

       -s speed
              The serial baud rate.  Supported baud rates are 0, 50, 75, 110, 134, 150, 200, 300,
              600, 1200, 1800, 2400, 4800, 9600, 19200, 38400,  57600,  115200,  230400,  460800,
              500000 and 921600.

       -?,--help
              Print  program  help  summary  on  stdout.  This option takes precedence over other
              options on the command line.

       -?,--version
              Print program version information on stdout.  This  option  takes  precedence  over
              other  options  on  the command line.  Use this option when sending screen dumps to
              Atheros Technical Support so that they know exactly  which  version  of  the  Linux
              Toolkit you are using.

ARGUMENTS

       file   The  name  of  an  input file.  No assumptions are made about the file based on the
              filename or extension.  Input files are not modified.

       stdout The name of a serial output device.  A error will occur if the device is not a true
              tty device according as determined by the isatty function.  Depending on the amount
              of input data and the baud rate, serial output may take several seconds or  several
              minutes.

EXAMPLES

       The  following  command copies files abc.txt and def.bin to stdout which must be an active
       serial device or an error will occur.

          # ttycat abc.txt def.bin > /dev/ttyUSB1
