The PortIO95 Parallel Port Interface
PortIO95 is a Windows 95 VxD that provides a simple Application Programming Interface to the PC Parallel Port. The PortIO95 VxD removes much of the learning curve associated with Windows 95 parallel port data I/O by wrapping complex system programming into simple function calls. For the programmers that need it, function calls that provide register based access to the PC’s parallel port are available.
PortI095 is a 32 bit VxD and will only operate under Windows95. It will not function under Windows 3.x or Windows NT.
The latest version of PortIO95 is V01.00 as of 03 Jan. 1998
