Hi dodochau,For many years now I have used the communications program from DNC4U. see
https://www.dnc4u.com/VERY simple to setup and use.Also reasonably priced as well.The person behind the software is also very helpful.The software does have a trial period where you can use it to see how it fits in for you.I have used the software on everything from Win XP through Win 10 so is compatible across all usual systems.Wiring diagram is in the help file within the software.I have attached a couple of files, one covering the parameter settings that I have used on our machines of the same vintage and one from Okuma on Serial Comms.CheersBrian.
