Now send-to-Rx adapters can be multiple. The string specified in registry's SendToRx
value should be semicolon-separated.
An example for one send-to-Rx adapter:
\Device\{754FC84C-EFBC-4443-B479-2EFAE01DC7BF}
An example for two send-to-Rx adapters:
\Device\{754FC84C-EFBC-4443-B479-2EFAE01DC7BF};\Device\{F5A00000-E19A-4D17-B6D9-A23FE1852573}
