This will let you review port's reaction to particular data and analyze results you receive.Īs you can see, Serial Port Monitor can be used not only as a great alternative to HyperTerminal but also as an efficient tool for development and debugging of serial apps and hardware. To be sure in the accuracy of your results, you can repeat sending the same data to the same COM port with a convenient session playback feature supported by the software. Additionally to Modbus data, with the app you can easily catch and log data communicated by RS485, RS422, and RS232 devices. Serial Port Monitor is fully compatible with Modbus RTU and Modbus ASCII protocols. All data received and sent by the ports will be recorded to a single log by using the first in, first out method. Connect your serial apps to several COM ports at a time and monitor the data exchange within one session. Simultaneous monitoring of multiple ports.Thanks to the Terminal mode option, you can easily emulate sending serial data (in string, binary, octal, decimal, hexadecimal, or mixed formats) to the required COM port like it was sent from the sniffed app.

Each of the modes provides data in the different format and you’ll be able to either choose the visualizer best suited to your needs or enable all four views at a time. The software supports four different modes of data display: table view, line view, dump and terminal views. If you are doing work on something slightly more modern it sounds like you should be more than fine.Advanced features offered by Serial Port Monitor So, just in case anyone else has the same use case, be aware of these issues. I've sent 2 support requests to the author but have not heard anything back - not sure if the help form works or not. I should say that the actual terminal emulation over the serial to USB connection works great - it's just the send/receive file part. Unfortunately I paid for the app after testing just the smaller transfers which worked for me that time. Kermit eventually times out on the board end and the file is there but 0 bytes. However, there appears to be a bug in either the CP2102 driver or the bundled Kermit - whereas on my Windows laptop with Terraterm I can transfer files without problem, with Serial nothing but the smallest (1-2K) text files will transfer. These two combined is why I bought the app. The bundled Kermit, XModem and YModem etc for sending and receiving files is also great.

As others have already commented, this makes this app unique and great for admins. I'm leaving a comment rather than a starred review as I don't want to drop stars for what must be a very edge case: I use Serial to connect to single board computers running (very) old operating systems, such as CP/M-80 and CP/M-68K.įirst, let me say that I love the integration of the drivers so that I can connect to the boards without having to install anything extra.
