Notes on Umslip
---------------

Umslip is a SLIP packet driver for use with Minuet and other DOS Internet
applications.  It is a class 6 (SLIP) driver.  Use Slipper with this if you
need a class 1 (Ethernet) driver.  See TCPIP1.FAQ in tcpdocs.zip to use
Slipper with the PHONE.EXE dialer.

To begin setup, issue SLIP SETUP at the DOS prompt.  Press F4 for modem
settings.  Select the Baud rate for your modem (if your modem does data
compression, set Baud rate here to 2 or 4 times your modem speed).  The
highest baud rate supported is 57600, so Umslip may not be a good choice for
a high-speed modem.  Select the COM port the modem is on.  You must either
have the modem on a standard port, or one of the following nonstandard ones:

   0x3e8  IRQ 2   is COM5:
   0x2e8  IRQ 2   is COM6:
   0x3e8  IRQ 5   is COM7:
   0x2e8  IRQ 5   is COM8:

Default Modem is HAYES, which should be fine.  Parity and Stop Bits should
be fine as is.  For Handshaking, CTS and RTS are both off by default; both
should be on instead, except for old modems without flow control.  Default
for Dialing is Tone, which is correct for me; select pulse dialing if you
have that.  Set Init str to your modem init string, minus the "AT" prefix.

Next press F5 for SLIP settings.  Fill in User Name, Password, and Phone
Number.  Note: If you use SLIP.BAT to connect, you'll be prompted for the
username and password every time anyway, but you might as well fill them in. 
PHONE.DOC says to make the User Name your full email address.  Give your
login username instead.

Exit PHONE.EXE, and issue this command at the DOS prompt:

   PHONE WRITE

That will create PHONE.CMD, which needs to be edited for your login
sequence.  At the bottom of the file is Procedure Host.UofM.Login, which
needs to be modified; the rest of PHONE.CMD should be fine.  Refer to
PHONE.DOC.  Be sure to uncomment the "Grab MYIP" line to get your IP address
from the screen.  That will cause the file PHONEENV.BAT to be created at
connect time.

Edit SLIP.BAT to configure dynamic IP when you connect.  Change this:

   :needsslip
   umslip -w >nul
   phone dial

   if errorlevel 1 goto nogo
   if %1. == minuet.  goto min
   if %1. == gopher.  goto gop
   if %1. == MINUET.  goto min
   if %1. == GOPHER.  goto gop

To this (for DOS 3.3 or later):

   :needsslip
   umslip -w >nul
   phone dial

   if errorlevel 1 goto nogo
   call phoneenv.bat
   echo my_ip=%MYIP% > ipaddr.cfg
   set ip=%MYIP%
   set $cutcp1=myip~%MYIP%
   if %1. == minuet.  goto min
   if %1. == gopher.  goto gop
   if %1. == MINUET.  goto min
   if %1. == GOPHER.  goto gop

Change this:

   :forceD
   umslip -w >nul
   phone force dial
   goto end

To this:

   :forceD
   umslip -w >nul
   phone force dial
   if errorlevel 1 goto nogo
   call phoneenv.bat
   echo my_ip=%MYIP% > ipaddr.cfg
   set ip=%MYIP%
   set $cutcp1=myip~%MYIP%
   goto end

If you don't have Minuet and PC-Gopher III installed in the same directory
with Umslip, you'll also need to modify SLIP.BAT to reflect the directories
where you have them.  For example, I change these lines:

   :min
   if %2. == . goto min1
   minuet /P=C:\MAIL\%2
   goto list

   :min1
   minuet
   goto list

   :gop
   gopher
   goto list

To this:

   :min
   if %2. == . goto min1
   cd \internet\minuet
   minuet /P=C:\MAIL\%2
   cd ..
   goto list

   :min1
   cd \internet\minuet
   minuet
   cd ..
   goto list

   :gop
   cd \internet\pcg3
   gopher
   cd ..
   goto list

Type "SLIP DIAL" to connect, "SLIP HANGUP" to disconnect and unload Umslip.

Some applications require a class 1 packet driver and won't work with
Umslip; it is generally better to use a class 1 driver such as Slipper. 
BOOTP works with Umslip if your provider has server-side support.
