[[Describe rxvt and the one Don distributes with [Expect].]]

----

I've seen the expect example, and it works amazingly well. What I would like to know is whether or not it's possible to get the same effect with pure tcl/tk. The acid test would be to run vi within a tk based emulator without  using the expect extension.

[RJM] Hm. Don't know exactly what you mean. But for the sake of this pages' title an example of an extremely simple terminal emulator follows here. You can adapt/extend it for your own purpose.
 set serial [open com1 r+]
 fconfigure $serial -mode "9600,n,8,1" -blocking 0 -buffering none -translation binary
 fileevent $serial readable {.t insert end [read $serial]}
 pack [text .t]
 bind .t <KeyPress> {puts -nonewline $serial %A; break}
The ''break'' prevents local echo of typed characters on the text widget.
