Virtual null-modem cables vs virtual serial ports: creation and usage
Many users who work with Windows Mobile serial applications joined by null-modem cable (especially if those applications require more than one serial ports pair) far more often face the necessity to create virtual serial ports. This functionality is more than necessary for GPS simulation programs. Generally, it allows to speed up development process during debugging and data-logging period. Therefore there comes an issue of how to create virtual com ports. In this article we will consider the program aimed at solving this solution: Virtual COM Port Kit which creates virtual serial ports and connects each pair of them via virtual null-modem cable. So, all data written to one virtual serial port can be immediately read from the other one, and vice versa.
The way it works: the program creates virtual serial ports and connects them via virtual null-modem cable. So any applications can exchange data just like they do it via hardware serial ports and real null-modem cables. In other words, it allows to connect two applications (like GPS simulation programs) over virtual serial ports.
For example, using Virtual COM Port Kit, it is possible to create pairs of virtual serial ports (e.g. COM7 and COM8) and connect two applications to them. All data that the first application writes to COM7 is read from COM8 by the second application, and vice versa.
Virtual COM Port Kit is able to:
- Connect serial applications via virtual serial ports. All the data written to one virtual serial port can be immediately read from the other one, and vice versa.
- It is a true virtual serial port driver. Virtual serial ports look and work exactly as real hardware serial ports.
- It’s built up for different platforms: Windows, Windows CE (ARM, MIPS, SH3, SH4 and x86).
Who can use Virtual COM Port Kit? The program is useful for users who work with Windows Mobile serial applications joined by null-modem cable (especially if those applications require more than one serial ports pair). For example, this solution can be used for GPS simulation programs. It allows to speed up development process during debugging and data-logging period. One can debug your program (which uses serial port) by connecting it to another program (e.g. serial device emulator).
Moreover if it is necessary to integrate virtual com port functionality, the program supports it. So one can create and configure virtual serial ports from your application directly.
General program features:
- Full hardware serial ports emulation
- Virtual serial ports look and work like real hardware ports
- Up to 9 virtual COM port pairs can be created
- Once created virtual ports are operable at each system startup (prior to user login)
- Virtual communication is more fast and reliable than via real null modem cable
- One click enable/disable button for all virtual serial ports
- Virtual serial ports are controlled directly from one’s own application using Dynamic Link Library (OEM license)
