Displays or downloads Network Terminal Accelerator (NTX) adapter configurations.
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 command is invoked from the /etc/rc.ntx file.
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 NumberOfPortsThese fields have the following values:
| Item | Description |
|---|---|
| MinorNumber | Specifies the board's minor device number. |
| Cluster | This field is always 1. |
| Item | Description |
|---|---|
| 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.
| Item | Description |
|---|---|
| -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. |
