TCPware is a third party layered product published by "Process Software LLC" of Framingham, Massachusetts to add TCP/IP capabilities to Digital Equipment Corporation's VMS operating system.
Meanwhile, many VMS users in governments, large corporations and universities were discovering the "TCP/IP based" internet and required third party software to enable connectivity to it.
Version 2.2, in 1991, added support for Sybase database procucts using the standard VMS functions.
It also added tn3270 for IBM 3270 terminal emulation, and support for the Simple Network Management Protocol (SNMP).
Almost as a "skunk works" project, it produced a layered product for VMS called UCX (Ultrix Communications Extensions) which later evolved into "TCPIP Services for OpenVMS".
