Hi,
Well, that is not the last version,
check here - v4.1 , and requires .NET Framework 2.0
I've test this one also while trying to find "the best" tool ;) capable to add tabs for PuTTY (
topic5016.html) and it seems that has no command line (Only GUI)...
Still any GUI can be manipulated to "support" command line using scripting like AutoHotKey or AutoIt
Which I intended to do for PuTTY with a tool from this list (
post16150.html#p16150)
The point is that GNS3 is calling the terminal application using command line and if a application looks great, but the developers have forgotten or didn't care about it, then that application can't be used (natively)...
PS: PuTTY for GNS3 has been improved to support specific features "required" in this scenario (Windows Only), except this tabbed window which is S.F. to me and requires a lot of recode, threads/windows management, etc... ;)
