Shipping was quite fast actually and in a week or so I had the new setup ready. With so much time invested I decided to get another C3 Mux and RS232 cable, this time, the problem must be with one or the other. NaHai said it must be a software problem, to purchase a plug-in HDD from them. When I restarted VMWare nothing worked again.

The green comm light came on the deskband!! Eureka.

The HDD came with TeamViewer and so one night in the wee hours I setup the system and after several hours (arg!) the Chinese tech operated Teamviewer and evidently changed some Config settings. After much screwing around and getting nowhere I finally contacted the vendor through their AliExpress contact portal. So the problem must be in the Mux itself or a cabling issue beyond the serial cable.
