Requirements
~~~~~~~~~~~~

This  program  supports  and  requires  Kickstart 2.04 (v37) or higher.  It
works on the internal serial port only.



What is it?
~~~~~~~~~~~

My system often calls out automatically via modem.  The UUCP software I use
sometimes  hangs  on a call.  It then sends error messages until I manually
abort the transfer.  This is very annoying since the call costs money.

ToggleDTR  is  the solution to those problems.  I use it to turn of the DTR
signal  for a few seconds when UUCico is spending too much time on a call -
causing the modem to hang up.



WARNING
~~~~~~~

This  program  is  a  *dirty*  hack.  It does access the hardware directly.
These are the things you should know before running it:

	· Blindly accesses bit 7 in ciapra of CIA-B to control DTR signal.

	· Checks left and right mousebutton for abort using the hardware
	  registers.

	· Does the inner loop while Forbid()ing multitasking to prevent
	  hazardous trouble on the serial port.
