Section Four
Making an Outgoing Call
To make an outgoing call manually, enter:
ATD 234 3456 [ENTER]
Where 234 3456 is the telephone number of the remote Modem. Spaces on the command line are ignored by the Modem.
There are a number of options that you can add to the dial command. Some of the more common are listed here. Refer to the ATD command for more information.
Tone or Pulse Dialling
To force either tone (touch tone) or pulse (rotary) dialling, include a T (for tone) or P (for pulse) after the ATD command but before the telephone number. You can set the default mode using the ATT or ATP command. For example, to set the default to tone dialling, enter:
ATDT 234 3456 [ENTER]
Wait for Dial Tone
This command instructs the Modem to wait for a given period (usually 30 seconds) to detect dial tone before dialling the telephone number. To wait for dial tone, enter a W just before the telephone number. You can also instruct the Modem to wait for a second dial tone by inserting the W in the sequence of numbers. For example:
ATDT9W 234 3456 [ENTER]
Dial Delay
With some telephone systems, you may need to insert a brief pause between digits in the telephone number. (The most common example is when you need to dial 9 for an outside line, wait a moment, then continue your dialling.) To do this, insert a comma in the telephone number where the delay should occur. For example:
ATDT 9,234 3456 [ENTER]
The default delay is two seconds but can be adjusted with the S8 register.
Note: The above two examples accomplish similar results through different commands; “ATDT9W” dials 9 and then waits for a dial tone before continuing, where “ATDT 9,” dials 9, waits a couple seconds and then dials whether there’s a tone or not.
