DTRON

 Function
  Turn on the serial port DTR signal.

 Syntax
  DTRON   No arguments are required

 Remarks
  This statement turns on the serial port DTR signal.  This statement
  should be used after you've used the DTROFF statement to hangup the
  modem when you need to hangup on a caller but don't want PCBoard to
  perform it's logoff processing.  Note that DTR should remain off for a
  period of time, to ensure that the modem has time to react to it, before
  turning it back on.  Consider 1/2 second (about 9 clock ticks) a
  reasonable delay.
