Thursday, July 17th, 2008

Software integrators, your time has come – Network Serial Port Kit update version 5.4.2 released. Now it’s possible to deploy the program over network!

It has updated user interface now and combines local virtual COM port functionality and network one. You can connect data collection serial devices: bar code scanners, modems, sensors, gages, RF equipment, telephone PBX systems, laboratory or industrial instruments, and so on – to the serial ports of your computer to deliver that data anywhere over any TCP/IP based network.

Connecting ActiveSync to Pocket PC Emulator Over Virtual Null Modem

Tuesday, May 27th, 2008

Tutorial MovieTo connect ActiveSync to the Pocket PC emulator you have to create virtual serial ports pair by using our Virtual Serial Port Kit product. The null modem scheme should be with full handshaking and DTR to DCD connection. That option is enabled by default. Serial ports COM1 through COM4 are the only usable ports within the emulator.


Different Null Modems

Tuesday, May 27th, 2008

There are several pinout schemes of virtual null modems. Three lines null modem (without handshaking) is simplest where only the data lines are cross connected in the null modem communication. It’s simplest and can’t be used in all circumstances because there is a problem, if either of the two applications checks the DSR or DCD inputs. These signals normally define the ability of the other side to communicate. As they are not connected, their signal level will never go high. This might cause a problem. As you can imagine, with this simple null modem no hardware flow control can be implemented. The only way to perform flow control is with software flow control using the XOFF and XON characters. Virtual Serial Port Kit doesn’t use simplest null modem. (more…)
