ATS27 Delay Before Dial

S Register 27 is used to define a delay of between 0 and 255 seconds which occurs after the D command is issued and before dialling commences.

This should only be used when you intend to implement callback security. Providing a delay between the dialling command and actual dialling allows the calling modem sufficient time to hang up before the modem begins to call back.

A 30-second delay should be sufficient time to allow most modems to hang up.

When you are not using security callback, this register should always contain a zero value.

UK Modems. Waiting 30 seconds may not work with UK telephone exchanges. Consult the supplier of your telephone line for a solution.
