SAL232 1.0.0 Sal232 is effective, user friendly utility when you need to analyze and log your serial communication. Received data are stored together with time marks that can be used to read time context. Specific details (time delay, Hex characters, etc.) are highlighted with various colors. Recorded data can be stored in .RTF file. It's only one .EXE file and no installation is required. It's distributed as freeware.

Very nice small tool if you want a quick look at the serial protocol. The timestamp which will is a nice feature. What I miss is a hex-view of the whole telegram.

Nice compact little utility which runs OK on Win 98SE - only has the one display mode in which printable characters are displayed as they are and non printable characters are displayed in green as Hexadecimal. The data I am trying to analyse contains no text so I would prefer to be able to choose for all data to be displayed and captured as Hex - seemingly not possible in this version. Would also like to be able to turn off time-marks. Nice program though, simple and effective.

Program performs well. I am not sure what the time delay is at this time. I am using the program to record NMEA output from a gps and fishfinder. I need to relate the depths to position, time is the common reference.Dick

Serial Comms review 1. easy to install on XP, Win98 machines of all vintages2. works with real serial ports or with USB/Serial converters3. only small issue is that you must decide on Baud/Bits prior to connecting other serial device, once connected must disconnect to change settings.

No connection to port Once the device was connected to the serial port the data logger could not monitor the port and if the data logger was pre-connected, the device would not connect.I was unable to use the program and do not have the time to figure it out.

SAL232 review I was looking for a RS232 snooper program that could time stamp the communication. SAL232 looks very fine, but lacks ability to adjust baud rate to user requested baud rate. My need is 10400 baud.

HW VSP is a free virtual serial port driver.

HW VSP 2.3 HW VSP adds a virtual serial port (COM5) to the system and redirects all communication over TCP/IP to remote IP address. HW VSP is free in unlimited version, it supports Windows 2000 and XP. HW VSP works with any TCP/IP device, it can work as a TCP server as well as a TCP Client. HW VSP supports remote RS232 port control (speed, parity, stop bits, etc..) over the RFC2217 (NVT).

HS COM 1.1 Serial Communications C Source Lib

HS COM 1.1 HS COM is a software library (with full C source code) that allows a calling user application to access serial communication ports (COM devices) under 32-bit MS Windows operating systems. It allows to transmit data, receive data and control line signals (such as RTS and DTR). HS COM library provides a convenient "packaging" to standard Win32 API by exposing only a few simple API services to a calling application
