The Program
Due to the response from the first program,
I decided to rewrite it to use the printer
port and a config file.This allows greater
control over the functions.
Repeat.exe is a DOS based program to control
repeater functions using a parallel port on a computer.
The features of the program are :

COR line input

PTT line output

Tone line input (for opt. CCST decode)

ID line output

Watchdog timer

Tail time with courtesy beep

The minimal requirements to run the program are :

XT or higher computer

256k or higher ram

one disk drive

one printer port

mono monitor (if you are interested in viewing the status)

As you can see the program was written to run on nearly
any computer An XT will need a time of day board for
the on screen clock to be correct, but does not need
it for the program to work.

Repeater.exe uses the following pins on the printer port:

Pin	Des.	Use
13	Select	Tone encode input
3	IO2	ID output
16&17	Ground
2	IO1	PTT output
11	Busy	COR input

When repeat.exe starts it looks for a program call repeat.cfg
in the current directory. If it does not find it, it will start with
the default nocall and turn the IDer off. Tail and courtesy will
both still be active. The screen shot below shows the config
file. You can turn the IDer on or off, the curtsey beep on
or off, and the tail squelch on or off.
