PPT talk button error: Failed to connect to COM4

[tobin]

You're really best off getting a serial comm to work. We reliably use a USB-serial adapter by Keyspan, which can be had any CompUSA and many other retailers.

That'd be my suggestion. But if you want to use VRPN with Vizard, however, you needn't deal with the CFG file because PPT acts as a VRPN server itself. You simply need to follow the instructions in the README file for the VRPN download. There is a problem, however, and that's that you have a version of PPT transmits a newer VRPN protocol than Vizard accepts. This is scheduled to be fixed by Q206 due simply to priorities. If it's important for you, simply say so and we'll schedule it for much sooner.
