The X window system provides terminal emulation for a VT102 and a tektronix 4015. There are two problems. First, I don't know anything about a tek 4015; it seems NOT to be a standard (e.g., 4012, 4014) tektronix, since it turns the output of the UNIX "tek" filter into garbage instead of graphics. Does anyone have either a modification of "tek" that will support tek 4015 control sequences or a list of tek4015 escape codes? Second, at least on the IBM RT-PC (BSD 4.2, IBM 6155 console) on which I have X, the VT102 emulation breaks for a window with more than 24 lines: the delete-line code seems not to work (to reproduce, make a window with more than 24 lines, make sure the environment TERMCAP entry has been updated with xsize, and run a vi in the window. Try to delete a line somewhere in the middle). Thanks for any help, davidra@lasspvax.tn.cornell.edu

A Tek 4015 is just a 4014 with an APL keyboard and a characer ROM which supports APL characters. Why the X window system would support such an obscure Tek terminal for emulation is beyond me. Are you sure it isn't a Tek 4105 (a small 640x480x3 color terminal) or a Tek 4115, another mainstream Tek color terminal? (I would be surprised to see 4115 emulation, since it requires an incredible number of environment calls to support features other than the basic graphics.) -- Robert Reed, Tektronix CAE Systems Division, bobr@zeus.TEK
