WSJT-X/HRDTransceiver.cpp
Bill Somerville 2099db5ea9 Tidy up DX Lab and HRD interface implementations 
Applied techniques  learned from  dealing with  HRD quirks  and TCP/IP
client   issues   on  Windows   to   the   DX  Lab   Suite   Commander
interface. These changes should hopefully make both the HRD and DX Lab
Suite CAT  interfacing more robust  in the  face of network  and other
latency issues or server failures.
