Entries with port numbers can be used as both ping targets and in the
friends’ list. The port numbers are ignored if not required by the
command or function.
Messages and response codes
The DART 200 provides information to the MAS concerning its
operation by response codes and messages. By default (X1) the modem
presents one of 10 response codes in verbose (textual) or terse (numeric)
format. If extended result codes are disabled (X0), only response codes 0
to 4 are available, codes 5 to 10 are mapped onto codes 0 to 4, as
appropriate. Disabling extended response codes is not recommended.

Messages
The only standard message that the DART 200 issues is:
INVALID NEI: CONTACT SERVICE PROVIDER
This means that the modem does not have an IP Address (NEI) stored in
it yet, so enter one before starting communications. It does not prevent
the modem from processing AT commands as part of normal modem
setup.
If other messages are encountered, contact modem technical support for
assistance.

NOTE:
Error codes 7 and 8 do
not apply to UDP,
because UPD is a
connectionless protocol
with no error feedback.
