AT COMMAND SET

Section 4

4-22

Pass through means that, if Xon/Xoff flow control is enabled, the controlling character

detected will be acted upon by any buffer it encounters, and then passed through to the

next buffer in the link. Disabling pass through means that any Xoff character received by a

buffer will be obeyed but the Xoff character will then be discarded. If line flow control is

enabled, the receiving modem line buffers will be susceptible to flow control characters in

the received data stream.

AT&W WRITE Active Configuration to NVRAM

Parameters : None

Default : None

Whenever power is applied to the DPX-213, or the modem is reset (ATZ), the status

registers are loaded with values saved in the non volatile RAM. AT&W allows a particular

configuration to be saved in the non volatile RAM and then reloaded the next time power

is applied to the modem or the reset (ATZ) command is issued. The interface speed is also

saved and becomes the default speed for the subsequent incoming calls (and after power

cycling).

AT&Z Store Telephone Number

Parameters : Dial String

Default : N/A

This command stores a dial string in non volatile RAM for dialling later with the ATDNn

command. Any valid dial string (see the ATD command) can be stored and up to a

maximum length of 36 characters. Any characters after this will be ignored. The storage

location to be overwritten by the AT&Z command is set by the ATN command.

To invoke the dial string type

atdnK

with no other characters. Dialling by pulse

or tone dial will be by the default or the last used method. The more general storage/access

command is ATNn&Z, which gives access to all 10 storage locations.
