NAME

       ttysend - Serial Line Rate Tester (Send)

SYNOPSIS

       ttysend [options] [<stdin]

DESCRIPTION

       Send  data to a serial device.  The primary purpose of this program is to send data over a
       serial port that can then be received with the ttyrecv utility.

       The ttysend program exits when either one of the following conditions are met:
           1.  The file specified on the command line (see -f) is sent in its entirety.
           2.  The send time specified on the command line (see -t) has elapsed.

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

COMMENTS

       This program does not yet support Windows platforms.

OPTIONS

       -f file
              The  file  to  send.   If this option is not specified, the values 0x00 to 0xFF are
              sent in a loop.  Instead of a filename, a '-' may be specified.  This is similar to
              the tar utility, and instructs ttysend to read from standard input.

       -l file
              The serial port file to send data to.  The default is /dev/ttyS0.

       -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.

       -t time
              Transmit for a maximum of time seconds.  The default is 15 seconds.

       -?,--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.

EXAMPLES

       None.
