Table 12-1: AT Commands in CDPD Mode (continued)

Command Description

Q[n] Quiet – Result Code Display Option

Controls the return or suppression of result codes to the local host (DTE). This will also affect the

framing of responses. See Section 4.3.3 for details.

Value Setting

0 Disable Quiet mode (enables return of result codes). (Default)

1 Enable Quiet mode (disables return of result codes).

Note: The CONNECT message is only partially affected by this command. The CONNECT

itself will be suppressed but the return of the caller’s IP address is still sent with spaces in place of

the word CONNECT. Also note that RING is suppressed by this command but the RI signal is

not. Use Quiet with caution.

Result Codes:

OK n = 0

Otherwise the result code is suppressed (n=1).

S[n]=[x] S-Register Write

Sets the contents of the specified S-register (n) to the new value (x). Zeros are assumed where

parameter values are omitted.

Var. Range

n Valid S-register number (See Table 12-4 for values).

x as determined by the S-register (n).

Result Codes:

OK S-register n set to x.

ERROR Invalid S-register value (n) or, setting (x) outside of permitted range.

S[n]? S-Register Read

The contents of the specified S-register (n) are returned to the host (DTE) as ASCII decimal digits.

Var. Range

n Valid S-register number (See Table 12-4 for values).

Result Codes:

OK S-register n reported.

ERROR Invalid S-register value (n).

V[n] Verbose – Result Code Form

Specifies whether the modem displays the result codes in numeric format or as words (verbose).

See Section 12.4 for a numerical list of the result codes. Note that numeric codes are returned as

ASCII character numerals. This command will also affect framing of responses. See Section

4.3.3 for details.

Value Setting

0 Numeric result codes.

1 Verbose result codes. (Default)

Result Codes:

OK(0) n = 0, 1 (The result code will be returned in the new setting.)

ERROR(4) Otherwise

X[n] Result Code Select

This command is supported for backward compatibility only. The modem takes no action. Any

parameter value is ignored.
