Black Box MD1641A Wait for New Dial-Tone W, Return to Command Mode after Dial Command Execution

SERIES II INTELLIGENT DATA/FAX MODEMS

Wait for New Dial-Tone W

A W inserted in the dialing command causes the Series II Modem to wait for another dial tone, and not resume dialing until another dial tone is detected.

It is not necessary to enter a W at the beginning of the dialing command to wait for a modem dial tone, because the modem will do that first (pause automatically).

In order for this command to work, you must select Wait-For-Dial-Tone dialing with the X2 or X4 command, so that your modem will be able to detect the dial tone.

Return to Command Mode after Dial Command Execution ;

A semicolon (;), entered as the last character of a dialing command causes the Series II Modem to return to the Command mode immediately after executing the command, instead of waiting for a carrier signal and going on line.

For example, entering ATDT5551212; would tone-dial the number, and do nothing afterwards except go back into Command mode. This can be useful in dialing applications where modem data transfer is not desired, such as voice communications, or in applications involving the use of touch tones as a data entry method, such as bank-by-phone.

Reverse the Mode of Operation R

In certain operations you may need to reverse the mode of operation for your modem from originate to answer or answer to originate so that it would answer the phone and go into answer mode. This command turns off the reversing function with the R0 command and turns it on with the R1 command with the modem in either command mode. If you want to reverse from the originate mode, use R (with no number) in the dialing string.
