COURIER HIGH SPEED MODEMS

"Dial the letters that follow (in an alphabetical phone number). NOTE: If you are including another command after the dial string, use closing quotation marks before the additional command.

!Transfer a call (flash the switch-hook). This command applies to modems in installations where other modems share the phone line. The modem flashes the switch- hook (goes off hook 0.5 seconds, on hook for 0.5 seconds and off hook again) to dial the specified extension.

WThis command is useful in situations where you must wait for a second dial tone before continuing dialing. For example, if you need to dial for an outside line, the Courier continues dialing as soon as it detects the next dial tone.

NOTE: This command executes only if result code option X3 or greater has been issued. If the modem is set to X2 or lower, the modem interprets the W as a comma (two-second pause).

@Wait for an answer (with X3 or higher). Some online services answer the phone and return a tape-recorded request for information before processing transactions. In such instances, the @ command can be used in the Dial string to tell the modem to detect at least one ring, wait for five seconds of silence at the other end of the call, and then continue to execute the Dial string.

To use the @ command, set the modem to X3, X4 or X7. If the modem is set to X2 or lower, the modem returns an ERROR message when encountering the @ character in a command string. If set to X5 or X6, the modem hangs up when it detects a voice answer and sends the VOICE result code.

/A slash (/) causes a pause of only 125 milliseconds.
