Virtual COM port driver
The driver works under Windows 9X/ME/NT/2000/XP systems and provides virtual COM ports to communicate via external hardware. It performs transparent conversion from custom hardware protocol to serial protocol what allows representing external devices as serial.
NI6052 Driver for Linux
Driver was designed to be a Linux counterpart of similar Windows-based driver provided by card manufacturer. The driver allows communicating with NI6052 data acquisition card and supports all advanced features provided by hardware card including Analog IO, Digital IO, Waveform generation, External triggering etc.
VirComm driver
VirComm driver provides virtualization of communication via selected Physical Serial Ports (COM ports) into set of virtual serial ports. Algorithms of filtering information between Virtual COM ports were defined in driver configuration file and allowed splitting mixed incoming traffic from hardware device into different streams (text, binary) which then were delivered to Virtual Serial Port, allowing devices connected to the Virtual Serial Port see only relevant traffic stream. Outgoing traffic received from Virtual Ports was mixed into single stream (with proper stream synchronization) and delivered to the Physical Port.
This effectively allowed for single hardware device to communicate via several streams of different format with PC applications, hiding all internal details of filtering inside driver. The rules for splitting traffic were defined for each serial port in a configuration file, so driver provided flexibility level necessary for supporting variations in stream formats.
Driver was implemented for Windows 2000/XP as filter driver. |
