PATCHING UUCP TO USE WINDOWS=7 ON MICROPORT V2.2

Microport Unix SYSV's uucico comes set at the factory for WINDOWS = 3, as do
most. Below is a method of changing this for those of you who do not 
have a source license. 

First, a small comment:
	If you are using PC-Persuit or other packet-switched network for
	uucp access, you WANT this patch. Our throughput doubled after
	installing it, from about 550 baud effective transfer rate to a
	little over 1100 -- probably the best you can achieve on a 1200 baud
	line.

Disclaimer & Notes:
	This method worked here -- after a long night of trying to figure
	out where to patch the hard way! The article posted a few days
	previous about this patch on a VAX was incredibly helpful in
	locating the proper point to apply the patch at. Of course, as with
	any modification, your mileage may vary and you should test
	the results thoroughly before trusting valuable data to it.

You will need:

1) MSDOS
2) Norton's Utilities or other similar package that can search and
   patch disk files (this is explained later)
3) Microport Unix.
4) About 15 minutes of your time.

To change to Windows 7:

1) Make another copy of uucico in /usr/lib/uucp in case you mess up.

2) Copy uucico to a dos DISKETTE (DO NOT use 'doscp' to a hard disk
   partition, there is a bug which can DESTROY the Fat table. It works
   fine to floppy media) The command you want to use is: 'doscp -b uucico A:'
   (See documentation supplied for more on doscp and it's devices).

3) Boot MS-DOS.

4) Bring up your file-zapper, and search for the sequence:
	c6 44 27 03 b0 03 -- there is only one occurrance.

5) Change both of the '03's above to '07', and write the sector back to disk.

6) Reboot Microport, and replace your uucico in /usr/lib/uucp with the
patched version using the command 'doscp -b A:uucico /usr/lib/uucico'.

That's it! You now have windows 7.

We've been using this for several days now, and have had zero problems with
it. As mentioned before, our effective baud rate essentially doubled.

Question: Why use DOS at all, and not 'patch'? Well, although patch documents
that it can use a hard address, we've been unable to get it to accept this
form of the command. Since uucico (and everything else) is stripped, you
cannot use a symbolic address.... thus the need for this route.

Enjoy, and happy PC-Persuiting!
