When entering a phone number into EssentialFax, you can enter additional characters that command the modem to pause. To do this, you enter these special characters in any part of the phone number or Dialing Rules
To cause a two second pause while dialing
Enter a comma (,) wherever you want a two second pause. You can use more than one comma. Each comma causes a two second pause before EssentialFax dials the rest of the number.
For example, if your phone system requires you to dial a "9" and then wait for four seconds before dialing a number, you would enter "9,," in the phone number. Every time you send a fax, the dial prefix is sent first, causing the modem to dial 9 and then pause for 4 seconds before dialing the fax number.
To cause an indefinite pause until the modem detects a new, or secondary, dial tone
Enter W wherever you wish the modem to wait for a new dial tone. The W causes the modem to wait for an additional dial tone before dialing the numbers that follow the W. The modem can be instructed to dial through PBXs (Private Branch Exchanges) or long-distance calling services that require delays during dialing by causing the modem to wait for a secondary dial tone and then dial.
For example, if your calling card requires you to dial 1-800-555-1212 and then wait for a new dial tone before continuing, you would enter "1-800-555-1212W" in the phone number. This causes the modem to dial 1-800-555-1212 and then wait until it hears a new dial tone before dialing the fax number.
It is sometimes best to use the Dialing Rules for this.
