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.
