About GPvNO


GP van Niekerk Ondernemings was established in 1986 as a Close Corporation developing software in the data communications field.

One of the first products to be developed was a serial terminal emulator named UTE. In 1989 a TCP/IP stack was added and the product was named INET TCP/IP and ran under DOS. In 1993 it was ported to Windows 3.1x and in 1996 it was completely re-written for 32 bit Windows and named WINET. It has since been constantly updated to keep track with new releases of Windows.

GPvNO is also active in the embedded systems market in partnership with Datalight Inc. SOCKETS, the Internet enabling subsystem of Datalight’s ROM-DOS product, is based on GPvNO’s RINET product. GPvNO also distributes the Datalight products in South Africa.

GPvNO is strongly committed to supply excellent service and support. Due to the feedback from our users and the active support we give them, INET has always been compatible with developments in technology.

Due to the advantage of local development, INET/WINET has excellent support and is very cost effective. With the active involvement of users we are able to supply new versions and bug fixes with very short turn around times, normally within days or even less. Compared to competing international software companies, we can often deliver an equal product at less than half of their prices with far superior support.
