Login script Tcl commands

As well as using Expect, the login scripts supplied with Secure Global Desktop make use of several Tcl commands. For example, the tarantella command connects to the application server instead of Expect and provides greater control over the connection. In addition, other Tcl commands are used, described here.

You can use these Tcl commands in your own login scripts.
