These applications allow reading and logging data from serial ports. They are able to monitor, capture and register all the traffic incoming through a serial port and some of them are also capable of dealing with multiple COM ports at once.
These programs can help you with what you're intending to do:
An application in .NET 2.0 that allows reading and writing from or to any serial port on a computer. This is a simple interface that reads lines from a serial port and allows writing single or multiple bytes of data to the serial port. Features: -Read from any serial port. -Automatic finding of current serial ports.
IPaNema reads any NMEA data from one of the serial ports (Com1-15) and delivers the NMEA data to any user selectable port and IP address using the UDP protocol acting as UDP server. It can also act as an UDP client, receiving NMEA sentences wrapped in UDP packets and outputs these to a serial communications port
RS232 Data Logger is an application used to register all the traffic incoming through a serial port (i.e. bar-code devices, mouses, serial printers, etc). It allows you to monitor multiple serial ports at the same time, the data is stored in an easy-to-read text file, for its later analysis.
Serial Port ActiveX Control is a powerful and versatile ActiveX component that lets you control serial ports, manage them and track their activity. It is a great alternative to complicated WinAPI for serial ports. In Serial Port ActiveX you will find diverse methods to read/write to and from serial ports, plenty of properties for advanced configuration of serial ports.
Advanced NMEA Data Logger inputs NMEA data stream from GPS, navigation or any other NMEA compatible device directly into file, Excel, Access, any database or another Windows application. Advanced NMEA Data Logger provides real-time data collection from any device or instrument.
