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.

refuse refunds if not happy I had my son purchase some software from this company and I asked for a refund, they just refused even if I was within my 14-day refund time, I suggest you try other companies, as this company, just don't think customer first

Serial Port monitor is one of the best I've been searching for a software to monitor serial ports and to troubleshoot them. I found many tools for that but eltima's one has it all: You can monitor everything that passes through serial ports even if they are already opened by another application or process. And that's really useful if you don't know anything about a new device. You can retrieve ports setting (BaudRate, Databits, parity,...) and also have logs of what transits between devices in different formats That can save you valuable time and efforts. Also you can check if connectors are correctly wired (DTR-DSR), (RTS-CTS), DCD. Sometimes serial malfunctioning comes from connectors not correctly wired or a detached pin This software is really versatile and robust. I highly recommend it.

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.

Money Back Guarantee Worthless As a first-time Customer of Eltima, we wered inspired to purchase their 'Eltima Player' Software due to their impressive 14-Day Honor-Based Money-Back Guarantee. Quoting from their Website: "Honor-based means we will be glad to return your investment providing that: we are sure the product is malfunctioning (i.e. doesn’t function according to the features declared at the product’s homepage or other official product documents) on the client’s computer/mobile device; we receive assistance in finding out the details of the problem on the side of the customer; we fail to address the deficiency within a reasonable amount of time. The same day of purchase we notified their Support team that the software was not functioning as represented. They requested a number of items (e.g. screenshots, etc.) which we promptly provided. They responded the next day with more things for us to do on our end to potentially fix the issue, which did not work – suggesting that this issue would be fixed in their next Release. We advised them that since their softward was malfunctioning, we wished to proceed with a full refund under their Honor Based Refund Policy. They refused suggesting that their software was fine, but that "The downloading function does not work because of the problem, on the YouTube side." completely casting aside the fact that is their job to update their software to resolve YouTube download issues". Bottom line: Don't be swayed by their Guarantee, as it is simply worthless.
