ZCOM C I/F Library Routines

ZLTMX (3X)

zltmx – Control logical terminal multiplexing

#include <zcom/zcomsys.h>

#include <zcom/zcomcall.h> /* if compiled with ANSI C (recommended) */

int32 zltmx (zap, mode)

zaddr_type *zap;

int32 mode;

Routine zltmx is used to enable or disable the multiplexing of logical terminals. This

routine allows dynamic control of the ZCOM_LTFLAG_OMX and

ZCOM_LTFLAG_IMX logical terminal flag bits. These flag bits are initialized for

each terminal ZLU by TTGEN, and may be changed by use of this call.

After calling this routine, the subsequent zrcvr and zsend calls will work according

to the new settings.

The libraries libzcom_c.a and libpthread.a must be linked into the calling program

by giving the options “-lzcom_c -lpthread” to cc(1) or ld(1).
