GOOD SOFTWARE BAD SERVICE Commander One Pro - the free version, Commander One is useless - is a well designed programme that simply works. I like it, as it makes it possible for me to upload files from my Mac to various storage clouds without any problems. However, I had to wait for twn days to get the Activation Code for Commander One Pro. Communicating with the developer, Eltima, is haphasard to say the least. Anyway, I finally have the Pro version working and this is OK. Yet please be ready to be disappointed in Eltima's customer service.

BEWARE! ELTIMA IS A SCAM I downloaded the airy program does not work they refused to provide a refund even after admitting the software did not work, the entire platform is a scam please be aware of this company and don't spend your money!

Eltima's Serial Port Monitor software is excellent. I wanted to connect a Digital Multi-meter fitted with an RS232C socket to a Raspberry Pi computer via a USB to Serial adapter (Prolific chip set) as part of a project to test the capacity of the batteries I use in my glider. This testing is an annual requirement. My problem was that I did not have documentation on the characteristics of the serial port on the multi-meter either in terms of the serial port setup or the protocol. I do have an old PC application ‘Dmmview’ that can read from the meter. I installed the evaluation copy of Eltima’s Serial Port Monitor on Windows 10 very easily and was able to trace the activity on the serial port the first time I attempted to do so. The trace gave me the basic information I needed to start to write the Raspberry Pi application in Python using the Python Serial module ‘pyserial’ 3.4. I now knew the port’s baudrate, parity, stopbits and bytesize (all non-standard). I also knew the data I had to send to elicit a response and the data that is returned by the meter. However, it did not work! I went back to the trace and found that the protocol also set DTR and disabled RTS. I added these calls to the program and lo and behold – I was able to read the required values from the meter. The Raspberry Pi application (that also involved interfacing to some relays) is now up and running I could not have achieved this without using Eltima’s Serial Port Monitor. George K.

Virtual Serial Port Driver Clear recommendation. The software is easy to install and does exactly what it is supposed to: provide COM ports. No compatibility problems whatsover under Win 7 or Win 10 or in various application programs (SDR radio etc.)

Purchased the pro version Purchased the pro version, the player wouldn't stream when it's clearly supposed to stream via airplay and DLNA devices, asked for a refund, and got denied because they only make refunds when the product is buggy.
