From: Mark Weiser <mark.umcp-cs@UDel-Relay> Date: 26 Aug 82 3:25:10-EDT (Thu) The following is forwarded from our Tek 4025 expert: The following is the 'usual' termcap entry for vi and so forth. It does not give you cursor motion; vi ends up faking it by moving the cursor a little at a time. It works OK for vi, but is rather slow. As a note, we have set our 'command character' to <escape>; it is generally convenient to do so. However, doing so would be incompatible with vi, so this script temporarily changes the command character to ^_ (code 037). It gets fixed and unfixed in the appropriate ways when you ^Z and % back and forth between programs.

I have kludged a way around it. First, include the following in your .login or .cshrc: if (`printenv TERM` == "4025") then alias kludge source kludge.scr alias unkludge source unkludge.scr endif Then, create the following three files: kludge.scr: setenv TERM kl setenv TERMCAP kludgetermcap echo "^[wor 30 h" echo "^[com 31" unkludge.scr: setenv TERM 4025 setenv TERMCAP /etc/termcap echo "^_com 27" echo "^[mon 34" kludgetermcap: #Kludge for Tektronix kl|kludge|kludge 4025:\ :is=\037wor 30 h\r:\ :bs:cd=\037dch80\037dli30\r:co#80:li#30:\ :ho=\037jum1,1\r:\ :cl=\037era\r:\ :nd=\037rig\r:up=\037up\r:\ :cm=\037jum%i%d,%d\r:\ :us=\037att u\r:\ :ue=\037att s\r: This has two disadvantages. First, you don't get a cursor; as we all know, (GRRR) when the keyboard talks to the host, there is no cursor in the workspace. Second, it doesn't quite do standout and underline mode right; as we all know, (GRRRRRRRR) changing the text attributes screws up everything to the end of the screen or the next attribute code. However, with this stuff, you can successfully play most of the games on the system, and 'ul' and 'more' work reasonably well. Hope all this stuff is useful. -craig stanfill-
