We are at an impasse.
Although we have run many experiments in the past with Arrington Viewpoint and SuperLab Pro, the serial port connection no longer sends strings to the Viewpoint computer (Windows 7 and Windows XP) from the SuperLab Pro (Windows 7 and Windows XP). The Baud rates and the com ports are the same. It has been tested out with and without internet access. We tried one system with SuperLab 4.0 but it was not working. We tried switching the COM ports without success. We turned off the firewalls on both computers, booted as administrators to the system.
