Hello Rob,
The program was written by David Rice KC2HO back in 1984. He is still in the
callbook. Try KC2HO@arrl.net, he might be signed up there. If not drop him a
line at his callbook address

Yes, the internal modem will work at 200 Hz. shift. Incidentally, the PK-232
was responsible for 200 Hz. shift RTTY. We didn't own the PK-232 when we
designed the DSP-599zx, but we weren't about to neglect the most popular
multimode data controller ever made! The AFSK demodulator and generator always
work at the same frequency. If you use the FSK generator in your transceiver,
it is probably restricted to one shift frequency in the vincinity of 170 Hz.

Try turning the DCD to zero if you are going to experiment with the burst
modes. The DCD is one of the parameters that were optimized for RTTY.

A few points of Interest.
Comp-RTTYII is a DOS based program which, without alot of flash, allows Solid
RTTY operation using even a basic 8088 machine. And does it very well.
Including some of the most convenient Message Buffers Ive used.
The RTTY Standard is 170hz Shift.
And has been for years.And Hence your Rigs FSK is set to 170hz.
The Pk232 was designed and built with 200hz shift as A COMPROMISE. In order
to
get the unit to do both RTTY and packet they had to fudge to make it do both.
So as a RTTY op you had to Straddle Tune a signal. Or heat up your soldering
Iron and remove/replace the filter components to restore the 170hz shift.
The Mod was quite popular and for good reason, IT WORKED and made the PK232 a
few notches above its unmodified form.

Subject: Software updates on the web
Creative Services Software has updates for the following products on our web
site today:
PakRatt CE. Version 1.01 includes a fix for callsigns greater than 8
characters. PakRatt CE is a FREE program that can be used with Windows CE
SH-3 and MIPS machines running Windows CE 2.x O/S.
http://www.cssincorp.com/pakrattce
Wefax '99 for Kantronics and AEA/Timewave TNCs. This updated version puts
both the Kantronics and Timewave versions at the same level. Both now work
in host mode, rather than terminal mode, can save, edit, rotate and flip the
picture, has an scheduler for automatic operation, and works under Windows
95, Windows 98, Windows NT and Windows 2000.
Wefax '99 is $49.95 until January 1, then the retail price will become
$59.95. For current owners of Wefax '99, this version on the web is a free
upgrade, as is all 1.x versions of any CSS software.

No you can't, read the licensing agreement. What's different here is that you
don't buy software, you buy a license for *you* to use it. Think of it like a
lease.
You can't resell a leased vehicle because you don't actually own it. Well, you
don't actually own the software either. All you've bought is a license to use
it.

It doesn't matter how the code is distributed. It is still the intellectual
property
of its author. He isn't selling you that. He is only selling you permission to
use
it. That permission is generally non-transferable, though there have been a
few
software companies whose license agreements did allow the license to be
transferred (Borland comes to mind).
