If anyone out there has experienced the following problem and found a solution we would greatly appreciate any help. We have a Sun 3/280 connected to the DDN using the Sun provided DDN interface. On the back side of the Sun we have a number of WYSE terminals emulating VT-100s. We are trying to connect from those terminals through the Sun and DDN to an IBM system using TELNET and SIM 3278 on the IBM. To get into the applications on the IBM we have to change our TELNET from character mode to line mode. However, once we are there we lose some functionality--mainly, we can't get cursor movement using the arrow keys; and using shift F3 does not do a screen print but just echoes. Those are the only problems we have identified thus far, but there may be others we have not encountered because of those two. We have tried turning the echo off until in the application and then turning it back on at the terminal. That was supposed to be a working solution, but no luck so far. By the way, the IBM is using the Network Solutions DDN interface package. Any solutions or suggestions are welcome. Thanks, John Wegl ~

Tn3270, which emulates a 3270 terminal, allows terminals (and the sun console itself) to be used as 3278 terminals on the IBM mainframe. You can get ahold of tn3270 from the Campus Software Office at UC Berkeley, (415)643-7201. Greg Minshall
