Setting up ATE

Edit online

Before running ATE, the system administrator must install the proper software (if needed) and configure the tty ports and connections.

ATE is an optional program product. All files necessary for operation of ATE are contained in the bos.net.ate program product available on the install media. Use the following commands to verify that ATE is available on your system:
```
lslpp -h | more   <return>
/bos.net.ate      <return>
```
If ATE is not available on your system, install the bos.net.ate image from the installation media (tape, diskette, or network server).
If ATE is installed on the system, a list of files associated with this program can be displayed using the following commands:
```
lslpp -f | more   <return>
/bos.net.ate      <return>
```
The user must have root user authority to set up the port for the communications device.

ATE uses both direct (cabled) connections and modem connections. Local RS-232C connections allow a maximum distance of 15 meters (50 feet) between machines, and RS-422A connections allow up to 1200 meters (4000 feet) between machines.

Before using ATE to call a remote system, verify that the remote system's tty device is ready to accept a call.

To prepare ATE to run on the system, perform the following steps:

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 using the smit mkdev fast path.
Select the terminal type to emulate with ATE and 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.
After 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.
