Terminal Adapter AT Commands & S-Registers
X5 Enables printing Calling Line Identification
(CLI) at the end of the CONNECT message
line. This command does not affect X0, X1,
nor X2.
Z Reset to Stored Profile
Values: none
Default: none
Resets TA to its current power-up profile and clears the command buffer.
The result is the same as turning the TA off and on. When you type ATZ,
the state of the &W command determines where default values originate.
&W0 defaults come from the customized configuration in NVRAM, and
&W1 defaults come from the factory default configuration in ROM.
Because Z clears the command buffer, it must be the last command in a
command string; normally it is issued by itself: ATZ. Note that whereas the
&F0 reset command always restores the factory default profile, the Z reset
command restores either the factory default or the stored profile, depending
on how the &W command is set.
&Cn DCD Control
Values: n = 0, 1, or 2
Default: &C1 (DCD normal)
Controls behavior of the DCD (Data Carrier Detect) signal. Normally, the
DCD goes high when the TA establishes a connection and drops when the
connection is lost. However, you can force DCD to remain high at all times
or to remain high except for a brief drop following a disconnect.
&C0 DCD is forced high at all times.
&C1 DCD goes from low to high when TA
establishes a connection (DCD normal).
&C2 DCD drops briefly following a disconnect,
then rises again. Register S10 defines how
long the DCD signal remains low after a
disconnect.
&Dn DTR Control
Values: n = 0, 1, 2, or 3
Default: &D1 (Exits Data Mode and reenters AT
command mode)
