Basic modem result codes

There are basic codes the modem will issue in response to processing an AT command. Result codes may be

displayed either in word (V1) or numeric (V0) format by using the Vn command. The Qn command controls if

result codes are issued (Q0) or not issued (Q1). The Xn, Wn commands and register S95 determines which result

code format the modem will display to indicate the type of connection established. There are more than 300

codes. The most commonly used are listed in the table below.

Numeric Verbose Description

0 OK The modem has received and acknowledged the command.

1 CONNECT Connection made at 300bps or extended result codes are off (X0).

2 RING An incoming ring signal has been detected.

3 NO CARRIER This result code reflects either an intended disconnect or a failure to complete a connection.

4 ERROR An invalid command was issued to the modem.

5 CONNECT 1200 Indicates a 1200bps line or DTE connection.

Table E.6: Basic Result Code Listing

Digital line guard

The modem has an optional Digital Line Guard Circuit that automatically detects an over current situation on

the Tip and Ring pins. When the modem goes off hook, it will immediately check the current on the Tip and

Ring pins. If the current exceeds 150 mA, the modem will display the “DIGITAL LINE DETECTED” result code

and then go back on hook. The modem will continue to display this result code until normal current is detected

on the Tip and Ring pins during an off hook condition. The DLG feature will protect the modem in case it is

accidentally connected to a Digital Telephone Line.

Sleep mode operation

The modem can be set to enter the low power sleep mode by setting ATS24=n. In this case, “n” is time, in

seconds, that the modem will operate in normal mode with no detected telephone line or DTE line activity

before entering low power sleep mode. The timer is reset upon any DTE or telephone line activity. If S24 is set

to zero, the modem will never enter the low power sleep mode.
