I have seen a few ways of doing this in the past and wanted to share the one I have been using for less than $20. I connected a HLK-RM04 serial -> Ethernet / Wi-Fi module to the fluke. Then configured it for a fixed address on ethernet. Then I run HW Virtual Serial Port software to route the com port on my desktop machine (running FIDE) to the address of the RM04. For this I use the HW VSP3 Single software. Works a treat, bi directional and over wired and wireless no dropouts or errors. More reliable than a serial cable has been for me in the past. 9600 baud, Even Parity, 1 stop, 8 data https://www.ebay.com/itm/Hi-link-HLK-RM04-Serial-Wifi-Ethernet-Wifi-Module-R S232-RS485-Module/253225173923?hash=item3af56583a3:m:mmzCM_wQDHUjy1_NCBrQFvw https://www.hw-group.com/software/hw-vsp3-virtual-serial-port This solution also works from within a Hyper-V Virtual Machine. I created one running Windows 7 32 bit to support the FIDE software. But I also verified today that running a Win 10 32 bit VM also works with FIDE and the VSP software (has to be 32 bit or the FIDE software and compilers won't work).
