Displays or downloads Network Terminal Accelerator (NTX) adapter configurations.
hty_load [ -d Device ] [ -f ConfigFileName ]
The hty_load command displays or downloads adapter configurations. If you issue this command without any flags, the system displays the current adapter configuration for the /dev/rhp0 device file. Given a Device parameter, the hty_load command loads a configuration file into the tty driver. The tty driver uses the file to configure both the host presentation services (HPS) and the adapters.
Typically, the hty_load commmand is invoked from the /etc/rc.ntx file. For more information about adapter configurations, see "Network Terminal Accelerator Installation and Configuration" in AIX Versions 3.2 and 4 Asynchronous Communications Guide.
The hty_load command uses a single configuration file to configure the adapters. Each entry is on a separate line. Entries are separated by new-line characters. Fields in an entry are separated by tabs or space characters. Entries in the configuration file have the following fields.:
MinorNumber Cluster NumberOfPorts
These fields have the following values:
|MinorNumber||Specifies the board's minor device number.|
|Cluster||This field is always 1.|
|NumberOfPorts||Specifies the number of hty devices. The number depends on the model of adapter you are using. The number of available channels is from 1 to 256 for a 2MB board or from 1 to 2048 for an 8MB board.|
The configuration file also supports comments. Comment lines begin with a # (pound sign). Everything to the right of the comment character is ignored. Comment lines end with new-line characters.
|-d Device||Specifies the raw device file name of the adapter. Use this option to override the default device name /dev/rhp0.|
|-f ConfigFileName||Specifies the driver configuration file name. The default configuration file is the /etc/hty_config file.|
This command returns the following exit values:
|>0||An error occurred.|
Access Control: You must have root authority to run this command.
Auditing Events: N/A
