Setting Up ATE

This article provides information on setting up Asynchronous Terminal Emulation (ATE).

The ATE program must be installed on the system. ATE is an optional program product.
The user must have root user authority to set up the port for the communications device.

To prepare ATE to run on the system:

Install an asynchronous adapter card in an appropriate slot in the system unit, unless the system has a built-in serial port.
Plug the RS-232C or RS-422A cable into the adapter card or the built-in serial port.
Add a tty device for the communications port. To do this, use the Web-based System Manager, wsm, or enter:
```
smit mktty
```
Select Add a TTY.
Select the tty type.
Select a parent adapter
Select a port.
Set the Enable LOGIN field to disable.
Set Terminal Type to HFT or dumb.
Make the necessary adjustments for the environment. The most common changes are line speed, parity settings, number of bits per character, and whether the line is to be driven as a remote or local line. Use BPC 8 and no parity if National Language Support (NLS) is required.
Set up the port for the device.
- To set up a port to call out with ATE, use the pdisable command. For example, to set up port tty1, enter:
```
pdisable tty1
```
- To set up a port so that others can call in, use the penable command. For example, to let other systems call in to the tty2 port, enter:
```
penable tty2
```
Ensure the device has previously been defined to the remote system. Once the device is defined, the ATE program must be customized to reflect the device settings on the remote system. Customize the default settings with the alter and modify subcommands or by editing the ate.def default file. To change the default settings for a telephone connection, use a dialing directory file entry.
