5.3.1 Disabling the RSLinx Driver for the Com Port on the PC
The communication port driver in RSLinx can occasionally prevent other
applications from using the PC's COM port. If you are not able to connect to the
module's configuration/debug port using ProSoft Configuration Builder (PCB),
HyperTerminal or another terminal emulator, follow these steps to disable the
RSLinx Driver.
