Affecting Port Mode

The port mode can be affected in the following ways:

•

It is affected by the port configuration in the ttgen configuration

.answ file that corresponds to the .tmem file used to bring up the

ACC MUX subsystem.

•

It can be affected interactively via the zterm utility.

•

It can be affected by an application program that calls the zconfig() or

zport() ZCOM subroutines.

•

It can be affected due to the watch daemon detecting that the ACC

MUX card can no longer communicate with the system in which it is

installed.

Each of these methods is described in the following sections.

In the TTGEN file, the mode of the MUX ports may be assigned in the

Port statements.

An example of configuring an 8-Channel port in RS-232 mode is:

When the zmon daemon is started (typically via zmasterd), the ports are

brought up in the mode that is configured in the .answ file which

corresponds to the .tmem file that is provided to zmon.

The port modes may be changed at any time, either through the zterm

interactive utility, or through a ZCOM application program. In order to

change the port configuration, the following steps must be taken:

1. All ZLUs associated with the MUX port must be disabled.

2. The port can then be reconfigured to the desired mode (i.e. Loopback,

RS232, E1RJ45, etc.).
