Chapter 3. Installing an Analog Modem
Terminal Emulation Modem Enable
An alternative method is to use a terminal emulation package such as HyperACCESS. In order to determine if an external analog modem is properly connected to the Express XRT, issue the AT command AT!Z (followed by Enter). If an external analog modem is properly connected to the Express XRT, the Express XRT responds with the message MODEM FOUND (shown in Figure
The AT!Z command is directed to the Express XRT not the analog modem itself. An ERROR occurs if the command is sent while the external analog modem is enabled.
If the external analog modem is not properly connected to the Express XRT, the Express XRT responds with the message NO MODEM FOUND.
