DIAL is a form of the TELNET program, and can be used to send or
receive data from a foreign host.

In its simplest form, DIAL is invoked by:

.DIAL nnn-nnnn		(where nnn-nnnn is the phone # you want dialed)

While running DIAL, almost everything you type is send over the modem
line.  However, a number of characters are trapped and used to make DIAL
do magic things.  Some of the most commonly used are:

βD    Open a file to receive data.  Everything coming in from the
      foreign host is appended to the data in the file.

αβD   Close the output file.

βI    Open a file for input.  Everything in the file is transmitted
      to the foreign host, just as if you had typed it.

αβI   Close the input file.

αβQ   Quit, close the DIAL connection, and exit to the monitor.

There are many more options than listed here.  See the Monitor Command manual,
both under DIAL(page 67) and TELNET(page 144-148) for more information.
