Win 3.1 with Trumpet Winsock

Manual Setup Instructions

Submitted by Doug Walsh.
                         Windows 3.1 and SLIrP
                         ---------------------
To use SLIrP and Windows 3.1, you need to have a software package that 
will allow you to dial into DelTech manually..the following instructions 
are for how to set-up and use Trumpet winsock..a shareware PPP dialer 
that you can obtain almost anywhere on the internet. Winsock will allow 
you to manually dial Deltech...then "exec" the slirp program..Winsock 
works really well using a script language of its own..and all the 
commands can be entered into the script...ie: changing HOPI to binary 
mode..the dialing..and logging in..all of it. Well..here goes..

	1. Obtain a copy of Winsock...use archie..or whatever to locate a 
	   copy of the file.
	
	2. Download it to your PC..uncompress it if necessary..or just 
           run it in a temporary directory.

	3. Get everything situated..setup the basics of winsock..it will 
           install for you. Run it and set all the settings in the setup 
	   option off the toolbar. (for help on this..see 
	   http://www.dtcc.edu/cs/slirp/)

	4. Once all these settings are done..use the 'dialler' 
	   option off the toolbar to run the 'setup.cmd' script. It will
	   be listed on the bottom of the option subwindow...just click 
	   on it. Answer it's questions..the answers are saved in a setup
	   file on your pc..and can be referred to as variables in the
	   script files.

	5. BTW: the settings I use for the inital setup..(under 
	  'file' then 'setup') are as follows:
		5a)IP address: 10.0.2.15; netmask:255.255.255.0
		   Default Gateway: 138.123.84.1 NOTE! The version 
   	           of winsock that I have..would not allow you to change 
		   the gateway from the setup screen..so to change it..I 
                   had to find the .ini file for winsock..and edit the 
		   gateway there.
		   Nameserver(for DNS lookups):138.123.84.240
		   DomainSuffix:dtcc.edu
		5b)The remaining paramaters can be left at default..or..to
		   help speed up things..and make the connection more 
	           efficient..you can 'tweak' them..my settings are:
			MTU:1500; TCP RWIN:8192; TCP MSS:1460; 
			TCP RTO MAX:60; Load Timeout:5 (secs)
			check the 'internal slip' box set the baudrate
			at 38400(you may need to slow this down..if 
			your modem can't handle it..but try the higher 
			baudrate first.
			check BOTH the CSLIP AND Hardware handshaking
			boxes.And the DCD box for online status detection
		
		6. For all these changes to be effective..you will 
		   need to restart winsock.

		7. Now comes the fun part..at this point..winsock is set
		   To call DTCC..and login..and that is it..as you know
		   We have to set our terminals..to whatever emulation..
		   and then login..and then drop back to the login
		   server to set our session into Binary mode..No problem
		   Right? Well it is for winsock..it is all done..as far
		   as it is concerned...using the script that exists 
		   at this point.

		8. I am not exactly sure what to tell you from 
		   here..you are gonna need to change the script to do
		   all this stuff for you..you can either do it yourself..
		   or mail me..(w32@hopi.dtcc.edu) and I will mail you a
		   copy of my script..you will hafta change your terminal
		   type (if you use something different that VT100) and 
		   you will probably need to change the modem 
		   initaliziation string, a cheezy init string will work
		   if all else fails..something like:atdt ...
		   what I did here was use the init string from another 
		   communications package..and just copied it into the
		   script.	

		9. Remember to exit and re-run winsock..to let all 
		   the changes take effect.

		10. Run Winsock..and watch the results on the screen
		    You should see it call..connect..login..password..
		    then terminal type..then drop the the login server
		    set the session to binary mode..then resume the
		    session..and it will "exec slirp" (the safe way).
		    Exec'ing slirp..will keep you from trashing your
		    account..plus it will lower the load on the server.

If all goes well..you are set..all you need to do is..start looking 
all over the internet for applications for winsock..there are 
TONS..Netscape..and telnet clients..the list is endless..and thay 
are all relatively easy to install..and pretty small too. Good luck!
