It is achieved by creating virtual serial ports, which are same copies as real one. Each application will think that it is working with serial port in exclusive mode. All virtual serial ports will be able also to send data to real serial port. Also, you will be able to set permissions to read, write or change control lines state for every application separately.<<less

HW Virtual Serial Port 2.5.10
HW VSP is a software tool, which adds to the operating system www.serial. more>> HW Virtual Serial Driver is primary designed for HW group devices, but it can be used for free as an universal driver to create a remote serial port,which redirects serial (RS232) data to the predefined TCP/IP address and port www.serial.
For special applications (ex. GPRS devices) is possible that the PC with the Virtual driver installed can work also as a server, so the connection might be initialized from the external device by sending any data to the remote port. The converter opens the connection with PC and sends the data to the virtual com. The whole situation is quite the same as with a normal serial port, but our device can be as far away as you want www.serial.
HW VSP can not be used to connect two physical ports of two PCs through the network (virtual null modem), because the HW VSP redirector works always with virtual serial ports.
If you are using the HW groups network devices with enabled NVT, you can change the Baud Rate, Parity and other communication properties (ex. binary inputs and outputs) during the normal communication using the RFC2217 standard, so you have a real remote port.<<less

Lalim Parallel Port Control Basic 3.4 is a powerful tool that ... through the parallel port (printer port) and can also control a remote PC parallel port throughLalim Parallel Port Control 3.4.0
Lalim Controls hardware through the parallel port and can also control a remote PC parallel port through a network. more>>
Most of engineering industry using PC to control hardware with using additional I/O card but with Lalim Parallel Port Control you can use your default printer port controlling external device such as switching on/off light or control electronic devices.
What does this program [does is] trigger the parallel port (Printer port) s data pin by your command. For example when you trigger pin2, your printer ports pin2 becomes +5 volt.
With this +5 volt, you can build your own electronic circuit to drive other external device. You can also built a simple circuit to test it by connect a LED with 1 kohm resistor direct to it pin.
Lalim Parallel Port Control requires a certain knowledge of electronics and if you are not comfortable with a soldering iron, or dont know what a 1k resistor is, then it is probably advisable that you do not attempt to use this program.
If you are capable working with DC electronics, Lalim Parallel Port Control allows you to build remote-controlled, or timed, devices for your home or office ? turning on or off the air conditioner, adjusting lighting, opening & closing windows, monitoring burglar alarms, and more.
