This is a pure Tcl package that implements a Tcl client. I wrote this because I needed to automate a telnet interface. In the past, I and others would use Expect for this task. While this worked, it was not always portable (especially to Windows) and it added another external dependancy to the application.
An html version of the man page can be found here.
tclTelnet is licenced under the BSD license.
The tclTelnet extension can be found here. This is pure Tcl so it should work on all platforms. I've tested it on Solaris, Linux, and Windows. A man page and an example (an interactive client) are included.
I welcome any feedback about tclTelnet. Drop me an email at todd.martin@acm.org. I also regularly read comp.lang.tcl and the wiki.
