DTR Drop-Dialing Operation

The TA128 will automatically dial the phone number stored in the
NVRAM when it detects an off-to-on transition of the DTR line.
Before you enable the DTR drop action, a phone number must be
stored and saved to memory along with an indication of which
number to dial on DTR drop. First use AT&Zn=s (n=0-39, s=phone
number) to store the phone number into NVRAM. Then, use AT*Dn
(n=0-39) to choose which of the in-memory phone numbers should
be dialed. Finally issue an AT&D1 to enable DTR drop dialing
operation.
O
Note: Phone numbers must include a prefix for specific call types,
e.g. I for ISDN.
An example of DTR drop dialing is given below. The destination
phone number is 5551234.
