Might help tell if it's really in the zsh code or maybe a bug in a tty driver. It looks like it may be impossible to track down remotely, but here are some other things you could jiggle to see; they are just random counsels of despair, really. 1. Try setting TERM to something different (e.g. vt100) 2. Try resetting the terminal before each line, for example precmd() { reset; } or precmd() { tset; } depending what you have available. 3. Try running `script' and looking to see if there's anything funny in the transcript of a short session. Chances are there isn't, since the problem with `return' suggests it's not just on output. In particular, does deleting (which you say brings the line back) show up as anything more than a ^H ? Also, when you need to type two returns to get it to work, do both show up in the transcript as ^M or only one? (If the option promptcr is set, you get a second ^M at the beginning of the new prompt anyway.) 4. Try recompiling with TTY_NEEDS_DRAINING defined to 1 (you can simply put #define TTY_NEEDS_DRAINING 1 at the top of zle_main.c since it doesn't seem to appear in the configuration stuff.) Can't see why it should be this, either, but then I can't see why it should be anything else. 5. If the two characters you do get on the line are after the prompt, maybe it's connected with the `clear-to-end-of-line' you get at the end of the prompt. Try setting TERMCAP (if that works on Linux) to: xterm|vs100|xterm terminal emulator:\ :am:km:mi:ms:xn:bs:pt:\ :co#80:li#65:\ :AL=\E[%dL:DC=\E[%dP:DL=\E[%dM:DO=\E[%dB:IC=\E[%d@:\ :LE=\E[%dD:RI=\E[%dC:UP=\E[%dA:ae=^O:al=\E[L:as=^N:\ :cd=\E[J:cl=\E[H\E[2J:cm=\E[%i%d;%dH:\ :cs=\E[%i%d;%dr:ct=\E[3g:dc=\E[P:dl=\E[M:ho=\E[H:\ :ic=\E[@:k0=\EOy:k1=\EOP:k2=\EOQ:k3=\EOR:k4=\EOS:\ :k5=\EOt:k6=\EOu:k7=\EOv:k8=\EOl:k9=\EOw:kb=\b:\ :kd=\EOB:ke=\E[?1l:kl=\EOD:kr=\EOC:ks=\E[?1h:ku=\EOA:\ :nd=\E[C:r1=\E>\E[1;3;4;5;6l\E[?7h\E[m\E[r\E[2J\E[H:\ :r2=@kf1=\EOP:rc=\E8:sc=\E7:se=\E[m:so=\E[7m:sr=\EM:\ :st=\EH:up=\E[A: (I've deliberately removed :ce=\E[K: from this.) -- Peter Stephenson Tel: +39 050 844536 WWW: http://www.ifh.de/~pws/ Dipartimento di Fisica, Via Buonarroti 2, 56127 Pisa, Italy
