I have a device called a DataSafe2 which provides an interface to allow storing data from a radio control computer transmitter in a file on a PC. The device has a serial port, and I plug it into an adapter that plugs into a UBC port. The adapter is supposed to be on COM 4. The system has worked in the past.
Currently, the computer cannot find the interface device. When I look at the COM Ports in Device Manager, only COM1 and LPT1 show up as having anything on them.
In addition to the DataSafe2 I have a WACOM (not currently plugged in) sketch pad, and a Palm cradle connected via USB.
How do I get my computer to see the COM4 port so I can use the interface?
