TCP SETMODE Functions and
CONTROL Operations
As a Pathway application programmer, you might need to know the Guardian operating
environment SETMODE functions and CONTROL operations used by the TCP. This
section describes the TCP’s use of SETMODE functions and CONTROL operations.
The Guardian Procedure Calls Reference Manual provides full descriptions of all
SETMODE functions and CONTROL operations. For programming information about
the SETMODE and CONTROL file-system procedures, refer to the Guardian
Programmer's Guide, the Enscribe Programmer's Guide, and the relevant data
communications manuals.
Table 9-1
describes SETMODE functions and CONTROL operations that the TCP
executes on terminal files when performing the indicated actions.
SETMODE Functions
SETMODE is used to set device-dependent functions. When you design an intelligent
device support (IDS) requester to communicate with a front-end process (FEP), you are
concerned with the SETMODE functions described in Table 9-2
.
