This program was recommended to me but I couldn't get it to work on Windows 7 Enterprise. It complained about needing administrative rights even though I am an administrator on this computer.

Excellent software, almost information overload! Very informative and helpful for diagnosing faults. Thanks!

Data received and sent through the port is conveniently displayed in a self-explanatory format in both HEX and ASCII. Good tool.

Just tried this on Windows 7 and it seems to do what I need. I'll comment further when I gain more experience.

It seems not working with 64 bit operating system.
Does it exist a dedicated software release?

Thanks in advance

Outstanding software. This monitor provided exactly what I was looking for - a method of simultaneously monitoring transmitted and received data entering or leaving the port while actually using the same port with a different application.

Wow!!!

In fact could not use it, kept crashing with Vista Home edition, even starting as administrator



Jason 2010-11-17 17:09:55 #
Version: 3.31

This worked well. Although downloading to a log was disabled in the free version, it gave you real time display of the serial port traffic as it was sent, and scrolled the history in a text box, so you could just copy and past it out if you wanted to keep it. It allowed me to solve my problem, so I'm a fan.

Hi , Its seems to be a very useful tool
as I can monitor whats actually going on
with Comms port.I use serial comms to communicate
with a variety of different equipment.

Thanks Mario

The software was used to capture Modbus RTU messages (hex characters) sent out a COM port. The software worked without issue, just what I needed.. and free too. I sent the captured results captured by Serial Port Monitor to CAS Modbus RTU Parser and got a readable file. Perfect.....

This software rocks, and I use it almost every day when testing serial data on the products we manufacture.
I only use the "data view" ability, but know this has some more powerful features I haven't tried.
I also do customer support over the phone and have had our customers download the software to help me troubleshoot their problems. When the com port isn't working, I can't tell from here, and this software comes in handy in SO many ways!
Thanks for such a great offering.

Greeting
Though your product is free but i dont feel it as user friendly because i was not able find any control to send or receive data on the Serial port. Could you please help me out by providing me the solution to do so. please dont mind i just want to tell the truth.. i had a similiar serial port monitor from Eltima Software if you could provide user interface like that product it would become more user friendly..
Thanks & Regards

I set up the "Free Serial Port Monitor" on a window machine and running the "CuteCom" on a linux box in parallel. The stream of data that receive in window machine is different from linux box.Don't have time to investigate but will try it later.

The best serial port monitor around. My team and I have been using it for over a year or so. It being free makes it that much better.

Thanks for a great product.

Too cumbersome. Not intuitive. Did not do the job I expected. Did not find it useful



Mgraham 2009-04-13 06:56:12 #

I used this previously for a Windows XP application,however, I needed to trouble shoot a problem on a Windows 98 system, and this software is not compatiable.

missing info

the sniffer misses protocol changes - baud rate, parity etc. in addition command timing is missing, i have a timeout problem i can't see with your tool. Thanks anyway.

Serial port monitor

It worked as designed. I was hoping to be able to break the data stream into packets by specifing the special characters that mark the beginning and end of the stream I was trying to view. I was not able to find a way to do that.

I'm using Vista 64 and receive the message that I have to install it as Administrator, while I run the setup as Administrator.



John Maurer 2009-02-16 13:33:26 #

Pretty handy tool

Wish I'd found this a couple of years ago when I was doing more RS-232 debugging. The way Free Serial Port Monitor allows you to capture and display your PC's serial port data while being used by another application is very handy.



Ralph.rastaetter 2009-02-14 11:07:43 #

It didn`t work for me.

It didn't work for me. I could run it, or the application I wanted to watch, but not both.

This is great - it just does exactly what I hoped it would - and it's free!!!



Mwilliams 2009-01-20 18:40:35 #

Works ok

I have used the software for about to days. It does ok. It did lockup my com port on shutdown a couple times. Can't say why. I'm just looking for char's sent back and forth.

very good

I needed a sniffer and was very pleased with your app, just one opinion:

in the COnsole View is to bad that only the incoming appears, and not the outgoing.

The rest I found it very good.

Sw Quality Engineer

Free Serial Port Monitor is the best tool the net offer to developpers. It's very simple to use and powerfull. I have just an only one suggestion to complete the features of your tool...it should be great if the tool offered the possibility to send messages/files/ through serial port. In this way I think the tool should be complete.



D.pickering 2008-09-17 18:06:07 #
Version: 3.31

Well done

No complaints. It did the job I wanted. I have not explored all the features of the product but the ones I used worked well.

Everything It`s Cracked Up to Be

The serial port monitor proved to be everything it was touted to be. It provides a very complete picture of what is happening with your COM ports. It allowed me to reverse engineer how to communicate with a 3rd party application by monitoring how another application was able to communicate. It saved me hours and hours of effort. An excellent tool.

Port Monitor with Data Capture Cards

I have been looking around for a simple and easy to use port terminal and checker for some gas analysers we are looking to send out into the field.
I downloaded the Free Serial Port Monitor on the off-chance that it would allow me to see that there was something on the other end of the serial cable and get some status information back from the analyser.
At the same time I was also keen to see whether the program could also detect and report on the signals from an Advantech PCI-1711L data capture card which also handles RS232 data.
Unfortunately in the short time that I played with this Port Monitor I was unable to get it to communicate with either the Analyser or the PCL Card ports. This may reflect the limited time that I applied to trying to use it, rather than any shortcomings on the part of the Port Monitor program.
It has got a very good set up wizard which allows you to set up the outputs and select the ports you want to look at.

Would like to see bytes in integer

Would like to view byte values in integers if possible. Would like to see packets between start and stop bits on separate lines. Good software though.

Use as troubleshooter

I downloaded your software here at work at Airbus to see about an RS485 to RS232 interface I'm troubleshooting. Looks very good so far with useful windows. Looking into connections still though.

Thank you.

Clean and easy

While developing some interface software between a Handheld PC and a Serial device this product made it incredibly easy to see the Tx and Rx from each device during implementation and testing.



Parkwachter 2008-03-07 14:07:25 #
Version: 3.31

Nice ...

I am not quite sure if this is the last answer to analyzing app-tapi-comx-(voice!-)modem chains, but who is interested anyhow anymore.

I'd like to know more about the above chain und FSPM helped.

Looking at the supplied viewers lets you get along.

Thank you for supplying!



Mortenfj 2008-01-31 04:17:58 #

It can`t log.

I really like the program it's fast and easy to use, but it would be nice to have a "log" function, so in case of a crash the data would be logged for recovery at a later time. But then again. It's free so who am I to complain.



johncc 2007-10-20 14:39:41 #

Handy addition to developer`s toolbox

Quite valuable when an independent monitor is unavailable.



AlexOD 2007-09-05 17:25:21 #
Version: 3.31

Did the job.

Just what I needed to monitor a VT100 terminal driver. Hex/ASCII view allowed me to see all escape codes etc.

Would like to see "analyzer" or "'scope" like trace of all handshake lines as I debug.

An Absolute Must Have

I've used lots of serial analyzers, network analyzers, and so on, and the Free Serial Port Monitor is one of the best of this kind of product. I solved a problem with a serial interface in a few hours that I can't imagine how I would've ever solved without it.

If you're doing work with serial interfaces on Windows, you have to have this!

Review on Serial Monitor

I have been using sofwtare for more than a year and I have enjoy using it. It is very easy and friendly to set up the sessions. I have got most of my co-workers using this serial monitor and they all have enjoy it.

You have dpne an excellent job.



StanH 2007-04-05 03:17:29 #

Simple program, does the job well

This program is easy to use, and has all functionality I need. The wizard makes it easy to set up a session, and the visualizers give all the information you need.

I used it to analyze a data protocol, and later I can use it for debugging too.

I needed a com port sniffer to analyze a communication between PC and a serial device (AC solar power inverter). This tool did the job after just a short and uncomplicated installation.
Use it!

Catching the culprit

I was looking for a "freebie" to check out a problem I am having with a random occurence in product control via RS-232. The monitor works really nice and is a lot more than I expected. I'm actually considering purchase of the standard version so I can use the logging feature instead of exporting data manually.

The problem I am trying to find has to do with serial responses getting out of sync with the respective queries. This happens randomly and for no apparent reason. What I needed was a log of everything that had happened previous to the problem, accumulate a number of instances for the problem and then compare the histories to see a common factor. The monitor does a good job of this and even provides time stamp info so it can be included in the analysis. Since the export data is format friendly, it is easy to pull back in and analyze with various tools.
