As shown in Figure 124, the following options can be set for
the Unit Emulator:
Dial out destination address
This field determines how the emulator will handle dial
requests from the serial port (ATDxxxx commands). The dial
address may be set by:
Fixed destination
Regardless of the value entered after the ATD command, the
emulator will always connect to the host specified in the Fixed
destination address and Fixed destination port fields.
From dial string
The emulator will parse the ATD command to extract the
destination address and port number. The examples below
show the two different formats that can be used to create a
connection to the address 192.168.2.200 and port number
6001.
Dotted Dial string is ATD 192.168.2.220:6001
Padded Dial string is ATD 0109020106080202020006001
From phone book
When a dial command is entered, the emulator will look up
the unit's phone book and attempt to translate the number to
an address and port number. More details on the phone book
can be found in section 7.9.
Accept incoming calls
When set, the emulator will listen for TCP connections on the
port number specified in the Accept port field. When a con-
nection is received, the emulator will indicate a ring condition
at the serial port. The equipment can then answer the call or
wait for the emulator to automatically answer. Once answered,
the emulator will indicate that the connection is open and
data will pass between the remote host and the serial port.
