AT Command Strings

For regular telephone lines, the default "Dial" string tells the modem that the line uses tone dialing. "ATDT"
is the command for a switch that requires tone dialing. If your switch requires pulse dialing, change the string
to "ATDP".
For ISDN lines, there are many more protocols and operational modes. Please consult the documentation of
your TA. You may need additional commands in both "Dial" and "Init" strings.
5.4.2 DTR Signal
The majority of WAN devices default to hanging up the current call when the DTR (Data Terminal Ready)
signal is dropped by the DTE. When "Drop DTR When Hang Up" is set to Yes, the ZyWALL uses this
hardware signal to force the WAN device to hang up, in addition to issuing the drop command "ATH".
