The TCP/IP Package for RT-11 is for versions 5.3 and later and requires a mapped monitor of the type XM (or ZM). Device handlers supporting the DEQNA/DELQA (EQ and NQ), DEUNA/DELUA (EU and NU), and DECNA (NC) are provided for the various devices and processor configurations. The selection of the appropriate device handler is dependent upon the RT11 version and processor configuration. A custom device handler may be built using the supplied conditional files. Options for building the EQ and EU device handlers in- clude the number of internal packet buffers, device timeout, in- terrupt processing at FORK level, mfps/mtps or PSW processor types, and optional spfun selection. The pre-built device handlers summarized in the following two tables were configured to operate with RT11 monitors sysgened to include timer and device timeout support. Timer support is re- quired for all TCP/IP Package programs and device timeout is conditionally required by the device handlers.
