VTTEST score card: scores the maximum 110 out of 110 points!
The VTTEST program tests the compliance to the VT100 standard of a terminal or terminal emulator.
It sends all sorts of devious sequences to the terminal which will break many programs (screen corruption, crash, hang).
The full details can be found on http://www.kermitproject.org/vttest.html
The VTTEST program itself can be downloaded from http://invisible-island.net/vttest/vttest.html#download.
If you want to run the test yourself, please make sure you first restore full VT220 compatibility for IVT which is purposefully broken in the default distribution to make it work best with most hosts out there…
Maximum VT220 compatibility can be set in IVT by choosing the “DEC-VT220” profile in the “Create session” dialog.
The VTTEST score card from the Kermit project has a maximum score of 110 points – 100 for basic functionality tests, 10 bonus points for special and extra features, some of which are not tested by VTTEST itself.
IVT scores 100 out of the basic 100, 10 out of 10 bonus points, for a total score of a perfect 110!
A few difficult ones are worth mentioning:
So, IVT scores 10 out of 10, making the total score 100 + 10 = 110.
The VT220 engine in IVT is shared by all protocols (Telnet, Kerberized telnet, SSH, Serial and Netbios, so it delivers the same accurate emulation regardless of the type of connection.
