Rn Reverse Originate/Answer Mode

MT3334HD8 User Guide

n = 0 or 1 Default: R0

The R command lets you reverse the modem’s mode of operation from originate to answer, or from answer to originate; for example, if you need the modem to answer the phone but then go into originate mode.

R (with no number) at the end of the dialing string reverses in originate mode.

R0 disables mode reversing.

R1 enables mode reversing when R is added to the dial string.

,Dialing Pause

Enter a comma in the dialing string to make the modem pause while dialing. This pause lasts two seconds (North American models) or four seconds (U.K. and International models) for each comma entered. You can force longer pauses by entering multiple commas, or you can change the length of the pause caused by a comma by setting register S8 to any value from 0 through 255 seconds (North American models), 4 through 7 seconds (U.K. models) or 4 through 255 seconds (International models).

Each comma in a dialing command counts as one of the 60 allowed characters.

:Continuous Redial

Enter a colon (:) as the last character of a dialing command to cause the modem to continuously redial the number, if it detects a busy signal, until the call is answered. North American models are limited to 10 redials. You must select smart dialing (X3 or X4) for this to work. (Not available in U.K. or International models.)

Note: This command has largely been superseded by software-based continuous redial features.

;Return to Command Mode After Dialing

Enter a semicolon (;) as the last character of a dialing command to cause the modem to return to command mode immediately after executing the command instead of waiting for a carrier signal and going online.

For example, type ATDT5551212; to tone-dial the number and immediately go back into command mode. The semicolon is useful when modem data transfer is not desired, as in voice communications, or in applications using touch tones as a data entry method, such as bank-by-phone.

!Flash On-Hook

Some switchboard systems react to a momentary on-hook condition. Insert an exclamation mark into the dialing command to cause the modem to “flash” on-hook for half a second, just as if you had pressed the switch hook on a telephone set for half a second. (With U.K. models, the exclamation mark causes the modem to flash on-hook for 90 milliseconds.)

For example, to flash on-hook to transfer to extension 5678 after dialing the number 555-1234, type ATDT5551234,,!5678. The commas cause a 4-second pause.
