Windows 3.x Support

Dialers: Trumpet Winsock

Trumpet Winsock is a program for connecting your Windows machine to the Internet. Trumpet Winsock uses a protocol that lets you use Internet programs with graphical interfaces. "Graphical" means they have pull-down menus, buttons, etc. (like Windows). Most people find this easier than the UNIX (also called "shell") interface which is text-based. Text-based means that all the commands and responses are given in text (like DOS), not by using graphical elements like buttons and pull-down menus.

Trumpet Winsock uses PPP (Point to Point Protocol), which is what makes it possible for the graphical interfaces to work.

• File Menu: The Setup Screen
• The Trace Menu
• The Dialler menu: 1.setup.cmd

File Menu: The Setup Screen

Pull down the File menu and choose Setup.

• Make sure the IP Address is 0.0.0.0 and if it is anything else, set it back to 0s.

  NOTE: This number is the IP address you get assigned when online, and so each time you dial in, it is a different number, which then resets back to 0s when you log out. If you open Trumpet while online the IP address field will "hold" the current address, which is a bad thing, because then next time you log in, Trumpet will try to find that exact IP address instead of taking the first available one. So make sure this is set back to 0.0.0.0 if it is anything else.

• Sometimes we change the MTU, TCP RWIN and TCP MSS numbers. Below are the settings we change them to. (This can greatly help when pages on the web are not loading completely, since this makes the packets of informaton smaller)

  Some people may have a setting of 1460 rather than 1450 for the MSS. Change that number back to 1450 if this is the case.

As a rule of thumb, 28.8 modems should get the first settings, 14.4 modems should get the 2nd set of numbers below. Real problem cases should use the lowest set of numbers.

MTU	TCP RWIN	TCP MSS
1490	4096	1450
1006	2048	966
552	2048	512

• Almost all of our users should have PPP protocol and have Internal PPP checked here.

• Slip port should be the Com port the modem is on.

• Baud rate should be correct for the modem speed.

• Hardware Handshaking and V-J Compression should be checked for all modems EXCEPT for 2400 modems. A 2400 baud modem does not support hardware Flow Control.

• Online status Detect is always None

• Close the Setup window.

  NOTE: You will need to close Trumpet and open it again for any changed settings to take effect.





The Trace Menu:

Nothing should be checked in the Trace Menu. If anything is checked, uncheck it.





The Dialler menu

Finally, under the Dialler menu, click on 1.Setup.cmd. There are 4 fields that come up, in this order:



Phone number is the number to dial into AEBC.



User Name is your user name, in lower case.



Password, your password should be entered here. There should be 8 *s there..



Modem Setup is where an init string for the modem goes.

NOTE: Older versions of Trumpet do not have the "Modem Setup" and an init string must be hard-coded (ie typed manually) into the login script. The line to find is either:


output $modemsetup\13

OR


output "at"\13

In that case, the user must type the init string into the script, for example:


output "AT&F&K3&Q5&C1&D2"\13


Be sure that the init string is in quotation marks, and be sure to have the line end with \13 to signify a carriage return.
