NetManage Inc, Cupertino, California developer of networking protocol software for the Microsoft Corp Windows environment has won agreement in principle that Mountain View, California-based X-terminal pioneer Network Computing Devices Inc will make a $4m investment in the company. A letter of intent also calls for the two firms to cross-license and resell each other’s products. Network Computing’s cash will buy a 10% stake in NetManage and wins a seat on the board for executive vice-president Judy Estrin. The move is described as part of Network Computing’s long-term strategy to become a broader provider of the elements of the network computing model. The cross-licensing pact calls for Network Computing to resell NetManage’s NEWT, a TCP/IP communication protocol stack for Windows-based personal computers, and its Chameleon and Chameleon/NFS complete TCP/IP application suites that bring Windows machines into the network computing environment. NetManage will in turn resell Network Computing’s PC-Xview X server products for Windows- and MS-DOS-based machines, and the PC-Xremote software, which provides high-speed access to remote personal computers over serial lines.
