- Note 1 : Some older Hayes modems supported the use of the ATCn and ATFn
- commands. On the V-series modems, issuing either of these commands with n not =
- 1 will generate an ERROR result code.
-
- Note 2 : When a command is issued without a number modifier, a zero is assumed
- (thus the command ATV is equivalent to ATV0, AT&C = AT&C0, etc.).

-
- The V-series Smartmodem 9600 supports the following result codes. Various
- combinations of forms, subsets, and display can be selected with the commands
- discussed in this section.

- 73 PROTOCOL: ERROR-
- CONTROL/AFT Error-control mode with AFT
-
-
-
-
- Note: CONNECT XXXX messages refer to modem-to-DTE connection speeds; CARRIER
- messages refer to DCE line speeds of the connection.
-
-
- Result Code Display
-
- Display of result codes for commands issued to the modem can be controlled
- with three separate commands.
-
- The Q command enables or disables result codes.
-
- Q0 Modem returns result codes (factory setting)
- Q1 Modem does not return result codes
- Q2 Modem returns result codes when originating a call; does not
-
- return result codes when answering a call
-
-
- Result Code Form
-
- The V command determines the form of result codes, whether they are returned
- as words (e.g., OK, ERROR, CONNECT) or as numbers.
-
- V0 Result codes displayed in numeric form
- V1 Result codes displayed in verbose (English) form (factory
-
- setting)
-
- For a comparative listing of numeric and verbose result codes, see the chart
- above outlining result code definitions.
-
-
- Result Code Set and Dialing Capabilities
-
- The X command selects result codes and enables dialing capabilities such as
- call progress monitoring.
-
- X0 Basic set of result codes (0-4) enabled
-
- The modem blind dials and sends the CONNECT result code once a satisfactory
- connection is established. Dial tone and busy signal are not recognized.
-
- X1 Result codes 0-5, 10-12, 14 enabled
-
- The modem blind dials and sends the appropriate CONNECT XXXX result code once
- a satisfactory connection is established. Dial tone and busy signal are
- not recognized.
-
-
- X2 Result codes 0-6, 10-12, 14 enabled; dial tone detected
-
- The modem waits for a dial tone before dialing, then sends the appropriate
- CONNECT XXXX result code once a satisfactory connection is established. The NO
-
- DIALTONE result code is sent if a dial tone is not detected within 5 seconds.
- Busy signals are not recognized.
-
- X3 Result codes 0-5, 7, 10-12, 14 enabled; busy signal detected;
- dial tone not detected
-
- The modem blind dials and sends the CONNECT XXXX result code once a
- satisfactory connection is established. The BUSY result code is sent if a busy
-
- signal is detected, but dial tones are not detected.
-
- X4 Result codes 0-7, 10-12, 14 enabled; dial tone and busy signal
- detected (factory setting)
-
- The modem waits for a dial tone before dialing, then sends the appropriate
- CONNECT XXXX result code once a satisfactory connection is established. The NO
-
- DIALTONE result code is sent if a dial tone is not detected within 5 seconds.
- The BUSY result code is sent if a busy signal is detected.
-
-
- Note: The NO ANSWER result code (8) is displayed only when a predetermined
- duration of silence expires when dialing a system not providing a dial tone.
- The display of this result code is independent of the X command. This result
- code is returned only when the @ dial modifier is included in the dial (D)
- command string.
-
-
- Negotiation Progress Reporting
-
- An additional set of result codes can be enabled to report progress of the
- negotiation phase of the error-control mode. These codes report the carrier
- speed (300-9600 bps) the link level protocol (LAP-B or AFT), and whether the
- link will be full- or half-duplex. These messages can also be reported in
- either numeric or verbose form. For example, both 72 and PROTOCOL:
- ERROR-CONTROL/LAP-B/HDX indicate that the protocol is extended LAP-B across a
- half-duplex link.
-
- W0 Error-control call progress not reported (factory setting)
-
-
- W1 Error-control call progress reported
-
- If the error-control link is negotiated, and a connection is made, the
- appropriate CONNECT XXXX message is reported.
-
- When in error-control mode, the CARRIER message may indicate one speed, while
- the CONNECT XXXX message reports another. The modem to DTE speed can be higher
- than the DCE line speed because of adaptive data compression and the capability
- of the modem to communicate with the remote modem at one speed and with the
- attached device at another.
