Just a couple of quick questions 1. I would like to disable the bells in VI ( caused , say, by two Esc), seems that 'set noerrorbells' doesn't stop the bell. What is the problem? If two Esc are not considered an error why ring the bell in the first place ? Am I missing something ? 2. I remember a while back someone mentioned ' visual bells' in Vi, that is instead of a bell the screen flashes should an error occur. Can someone tell me how to do this ? Any help is greatly appreciated. ---------------------------------------------- ARPA: zhao@csd4.milw.wisc.edu BITNET zhao%csd4.milw.wisc.edu@wiscvm.bitnet UUCP uwmcsd1!csd4!zhao

This has to be defined in the TERMCAP (file or environment variable). Below is my entry for a CIT101 terminal. When you want to put these commands in a file, don't forget you must use 'source file...', otherwise the environment of the subshell will be set only. Please note the 'vb' entry, This will reverse the screen, send some NULLs, and reverse it again. setenv TERM cit101n setenv TERMCAP 'd1|cit101n:al=\E[L:\ :am:bs:cd=\E[J:ce=\E[K:cl=\E[H\E[J:cm=\E[%i%d;%dH:co#80:\ :cs=\E[%i%d;%dr:dc=\E[P:dl=\E[M:ei=:ic=\E[@:im=:kd=\E[B:\ :kl=\E[D:kr=\E[C:ku=\E[A:li#24:nd=\E[C:pt:se=\E[m:so=\E[1m:\ :ue=\E[m:up=\E[A:us=\E[4m:\ :vb=\E[?5h\200\200\200\200\200\200\200\200\200\200\200\200\E[?5l:\ :xn:xv:k0=\EOP:k1=\EOQ:k2=\EOR:k3=\EOS:k4=\EOw:k5=\EOx:k6=\EOy:\ :k7=\EOm:k8=\EOt:k9=\EOu:l0=PF1:l1=PF2:l2=PF3:l3=PF4:sf=\ED:\ :sr=\EM:vs=\E[5v\E\=:ve=\E[4v\E>' -- Karel van Houten BITNET : NO!

'vi' does not only communicate by writing (admittedly, not very much unless programmed otherwise) on the screen but also by sounding the bell. ESC ESC is a safe way of *always* getting into the command mode. The experienced typist relies on the audial signal from 'vi' to confirm this and doesn't have to use his/her eyes. Hence, the 'vi' bell is *not* to be considered an error indication only! >2. I remember a while back someone mentioned ' visual bells' in Vi, >that is instead of a bell the screen flashes should an error occur. >Can someone tell me how to do this ? In your terminfo (or termcap) file you add a 'flash' entry (e.g. escape sequences to temporarily change the screen to reverse video and back) and in your EXINIT (or .exrc file if you use such a thing) you do :set flash. In 'vi' you can disable flashing by :set noflash. The side effect is that the terminal will be initiated by your 'tset' to flash instead of sounding the bell to indicate errors also in your shell. Personally I use flash all the time. It is *much* nicer to the guys in the offices next door ...

Warning: usually, such entries assume that your terminal is operated in a particular B-on-W or W-on-B state; if you use reverse video when that's the opposite of what the termcap/terminfo entry assumes, the first visual bell will toggle your B/W mode.
