     The most common error that you will see is #62.  This is usually caused
by the CFG file not having enough lines.  I have included this list so
that you may be able to fix a problem that occurs with a PAROLE Software
door.

486DX CPU's
-----------
The math coprocessor in 486DX CPUs cannot handle floating point math which
all MicroSoft Basic's use. This can show up as an ERROR 5, a keyboard 
timeout, etc.

Fortunately there is an easy fix for this problem. Simply place the following
line in the AUTOEXEC.BAT file:

SET NO87=ON

This will inform DoorFrame to use a different timing routine.  If you are
operating under DESQview/X, you must flag the MATH COPROCESSOR as being ON.

If the door seems to operate fine on  the BBS end but the remote cannot
receive or receives garbled info, check and make sure you are passing the
correct IRQ to the door.  Com 1 and 2 are standard and as such, you do
not need to pass the IRQ to them.

If you are operating under DESQview, you will need to load DVANSI in
each window.

Error #75 is usually an incorrect path and/or filename in the CFG file.
Please check the filenames and paths in your CFG file(s).  They *MUST* be
correct in order for the door to operate.

Unless you are using a Digi-board and need a fossil driver, DO NOT use
the "/FD" switch on the command line.  The doors do not need a fossil
driver to operate on serial ports.
