Table 10: Hayes dial-up extension numbers
The <address> and <extension> sections of the ATD command can include any number of colons,
dashes, or spaces as these will be stripped out of the string by the radio.
If the radio receives a character on the serial port while dialling is in progress it will immediately terminate
the connection attempt and send a NO CARRIER response message.
If a connection is established then the CONNECT response message will be returned.
ANSWERING
The RFI-9256 provides two options for answering dial-up calls:
 Auto-answer . When in auto answer mode and a connection request is made the RFI-9256 will
output a configurable number of RING responses on the destination radio and extension, and then
automatically connected. When dialling an extension other then the main or auxiliary port, auto-
answer is used by default.
 Manual answer . When in manual answer mode the RFI-9256 will output a RING response on the
destination once per second until the ATA command is received at which point the connection is
established. If no ATA command is received within the connect timeout the connection is not
established.
