Appendix L: AT Command Summary (TA)

How To Use AT Commands

Usually, your data communication software controls the ISIHI-2S/2U terminal adapters

for you. However, you may also want to use AT commands, which give you complete

control over the TAs. Be careful using these commands because

loose its ability to control the TA. If you find that an AT command causes a problem, turn

the computer off and then back on to reset AT commands to the factory default settings.

You also can type AT&F to return to the factory default setting.

To use an AT command, you must first:

1. Run your communication software.

2. Configure the software for the appropriate COM port and IRQ settings, if necessary.

3. Enter Terminal mode (aka Command mode, Local mode, or Direct mode). This is the

mode in which most datacommunication software packages start up. Type the AT

command and press ENTER. For example, type ATH0 and press ENTER to hang up

the TA connection or AT&V and press ENTER to display current configuration.

Most AT commands can be entered in strings (on the same command line) without spaces

between the individual commands. For example: AT&VH0 <ENTER>.

The TA usually returns a response (or Result Code) at the next line if it understands the

command. The response usually is OK or ERROR unless the AT command provides other

(extended) messages.
