Sr?

Function:

Read Register Value

Values:

r = S-register number

Default:

None

register. See S-Registersin this chapter for further information.

Command: Vn

Function:

Terse/Verbose Result Codes

Values:

n = 0 or 1

Default:

V1 (Verbose)

Description: Use V to control whether the TA’s result codes display as digits (terse) or as

 

words (verbose). (Use Q to enable or disable the display of result codes.)

 

V0

Enable terse result codes.

 

V1

Enable verbose result codes.

Command: Xn

 

Function:

Connect Messages

Values:

n = 0, 1, 2, 3, 4, or 5

Default:

X2 (Enable all messages) and

 

X4 (Disable printing CLI with CONNECT message)

Description: Use X to select which result code messages the TA sends to the computer.

X0 Enables messages OK, CONNECT, RING, NO CARRIER, and ERROR (terse result codes 0–4).

X1 Enables all messages except BUSY (terse result codes 0–5, 10–14, 17–19, 28, and 32). If a call is placed to a busy line, the message NO CARRIER displays.

X2 Enable all messages (terse result codes 0–5, 7, 10–14, 17–19, 28, and 32).

X3 Enables all messages EXCEPT it does NOT print protocol messages. For example, for a V.120 connection, X2 prints:

CONNECT 64000/V.120

For a V.120 connection, X3 prints only the connect message (and speed):

CONNECT 64000

X4 Disables printing Calling Line Identification (CLI) at the end of the

CONNECT message line. Does not affect X0, X1, or X2.

X5 Enables printing Calling Line Identification (CLI) at the end of the

CONNECT message line. Does not affect X0, X1, or X2.

Command: Zn

Function: Reset to Stored Profile

Values: none

Default: none

Description: Resets TA to its current power-up profile and clears the command buffer. The result is the same as turning the modem off and on. When you enter ATZ, the state of the &W command determines where the default values originate. The &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.
