Black Box MD1641A, MD1640A manual Result Codes Verbose/Terse

SERIES II INTELLIGENT DATA/FAX MODEMS

Result Codes (Verbose/Terse) V

The V command controls whether the Series II Modem’s result codes are displayed as word (“verbose”) or single digit (“terse”) messages.

For example, if after dialing, no carrier signal is detected, the resulting message can be displayed either as NO CARRIER, or as the digit 3.

Entering ATV0 (or ATV) causes the Modem to display the Result Codes as digits, while ATV1 displays them as words. If you do not select a method, the factory default setting causes the modem to display Result Codes as words.

Result Codes (Basic and Extended) and Call Progress Selection X

The X Command is used to select one of two possible dialing methods (“dumb” or “smart”), and to select various response combinations related to these methods. You can choose to have certain responses suppressed, or whether or not you want speed indications along with the CONNECT responses. You can also pick and choose certain responses in order to match up with “Standard AT” responses. (Refer to Appendix G for a summary of Result Codes.)

The Series II Modem provides “Basic” and “Extended” Result Code sets. The difference between the two is the Basic set provides one response (CONNECT) to indicate a connection, while the Extended set provides several responses for different speeds (CONNECT, CONNECT 2400, CONNECT 4800, CONNECT 9600, CONNECT 14400, CONNECT 19200, CONNECT 21600, Etc.).

When the Extended set is chosen, you also have the option of matching them up with Standard AT 2400 response code sets, by including or not including the BUSY and/or NO DIAL TONE responses while excluding the DIAL TONE response. The X command is used to select which responses are provided.
