OUINET Dialup
How to Access the IBM System

This access method is only associated with OUINET-A which is being removed from service in 2002.

• Why is the IBM computer connection special ?
• Your typical terminal and PC communications are asynchronous ASCII transmissions. Most ASCII asynchronous equipment displays each character when received and transmits each character as you type it. Much of the operation of the IBM system is based on filling a screen with data and then sending the entire screen. Historically, IBM used screen formed EBCDIC synchronous transmissions and did not use ASCII asynchronous communications. Something needs to translate between these two methods of communication.

• What is OUINET DIALUP doing that is different for the connections to the IBM ?
• Just like your PC is running an emulator to simulate a terminal, OUINET DIALUP is running an emulator to simulate a synchronous EBCDIC terminal. OUINET DIALUP runs a program to emulate an IBM 3270 Model 2 terminal. If the IBM software you wish to run does not support the 3270 Model 2, you cannot use it directly from OUINET DIALUP.

• What does my equipment need to do ?
• Your software needs to emulate a DEC VT100 terminal. Most terminal emulators will support emulation of this popular terminal. The Kermit software available from the University Computing Support Services Help Desk (at no cost) will provide the necessary emulation. Your keyboard and PC software also needs to be able to map' special keys that appear on a 3270 Model 2 to keys that you have on your keyboard. Below is a list of special 3270 function keys and the corresponding ASCII codes that you will need to send to trigger the desired function.

• What if it doesn't work ?
• If you can connect to other systems without problems, your PC terminal emulation keyboard mapping is probably incorrectly configured. Review the manuals for your software emulation product. Contact the University Computing Support Services Help Desk (337-482-5516) to obtain a version of Kermit configured for 3270 emulation.

• How Do I Read the Table Below ?
• The first column is the name IBM uses for the key. The last column is an abbreviated description of the function. The middle column describes what character to send to obtain the function. CTL-? is a control code. ESC is the escape key, ESC-? is the escape key followed by another key, ESC-(CTL-?) is the escape key followed by a control key. The symbol \0 , where is a single digit means send octal code .
