ttysig(1)                                    Qualcomm Atheros Open Powerline Toolkit                                   ttysig(1)

NAME
       ttysig - Serial Line Signal Controller

SYNOPSIS
       ttysig [options]

DESCRIPTION
       Interactively  control  serial  line output signals (Request To Send, Data Terminal Ready), and read the current value of
       all control signals (Request To Send, Clear To Send, Data Set Ready, Data Terminal Ready, Data Carrier Detect, Ring Indi‐
       cator).

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

OPTIONS
       -s device
              Specify the serial device used.  The default is serial console device "/dev/ttyS0".

       -D value
              Set the serial control line DTR high if value is non-zero, low otherwise.

       -I     Interactive mode.

       -R value
              Set the serial control line RTS high if value is non-zero, low otherwise.

       -r     Print serial control line status on stdout.  This is performed after -R and -D.

       -?,--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
       The following example sets DTR high and RTS low at program start.  The user then interactively prints the current control
       signal values, and then sets DTR low.  Since no serial devices are specified, program defaults are used.

         $ ./ttysig -I -D 1 -R 0
         command (D #, R #, r, q): r
         RTS: -V
         CTS: -V
         DSR: -V
         DTR: +V
         DCD: -V
         RI : -V
         command (D #, R #, r, q): D 0
         command (D #, R #, r, q):
