5.0 Hayes Emulation Mode
• ! — Initiate Flash. The ! command causes the Modem to go on-hook for
1/2 second. The command has the same effect as holding the switch-hook
button on your telephone down for 1/2 second. Some PBX systems use a
flash to transfer calls.
• &F — Recall Factory Configuration. The &F command restores the
Modem to its original factory configuration, using data stored in ROM.
However, the change is not permanent. If the Modem is turned off or
reset, the recalled configuration is replaced with the default stored
profile. (See &Y command.)
• &V — View Active Configuration, etc. This command displays the active
modem configuration, user profiles stored using the &W command, and
phone numbers stored using the &Z command. When &V is invoked,
the DTE displays the configuration commands last issued, including
parameters used, and the values currently stored in the S registers. The
&V command should be issued as the last command on a line.
• &W — Write Profile To Memory. The &W command saves the
storable parameters of the Modem’s active configuration by writing the
configuration profile to non-volatile memory. By selecting either &W0 or
&W1, two different user profiles can be saved (profile 0 or 1). One
of these profiles is automatically restored whenever the modem
is powered on or when the Z command is issued. (See &Y and Z
commands.)
The &W command cannot be used to write changes to the user profiles if
the Modem’s front panel is disabled with the Front Panel Control option.
The parameters listed below cannot be stored—all are set by changing S
register values (as indicated in Table 5-3):
Backspace character (ASCII 08)
Carrier-detect response time
Carriage-return character (ASCII 13)
DTMF tone duration
DTR detection
Escape-sequence character (ASCII 43)
Escape-sequence guard time
Line-feed character (ASCII 10)
Lost-carrier-until-hangup time
Pause duration (effected by comma)
