c
- To free a service profile for use on another interface, use the AT^SISS command and select service type
= "none". This action deletes the entire profile and restores all parameters of the profile to their initial
power-up state (all values are empty). For example, to remove the service profile 3, set AT^SISS=3,srv-
Type,none. After this, a new profile 3 can be created on any other interface.
Address notation
Server addresses must be provided as IP addresses in stan
dard dot-format (e.g. "192.168.1.2") or as server
address names resolvable by a DNS server (e.g. "smtp.myserver.de" or "pop3.myserver.de").
Timeouts
Timeouts are not part of the Internet AT command function
ality implemented in BGS2T and, if desired, are the
responsibility of the host application. It is recommended that the host application validates URCs and AT com-
mand responses and reacts adequately, for example by sending a close message or starting a timer.
Socket service used with UDP protocol
The significant differences between th
e TCP and UDP protocols imply that UDP sometimes requires particular
procedures or even specific parameters. Details on how to handle UDP services can be found in extra notes or
are included in the general parameter descriptions.
Using the DCD line to detect the connection status of Internet services
With AT&C you can configure the DCD line of the used serial interface to indicate whether an Internet service is
active. For Socket, HTTP, SMTP and POP3 the states "Up" or "Connecting" are indicated, for FTP and transpar-
ent TCP only the state "Up".
