future connections until an AT#GPRS=0 command is issued or the network requests a context
closing.
2.1.3 FTP Client
On top of the embedded TCP/IP stack, an FTP client is available. Such FTP is a versatile protocol
suite, designed to be powerful, compact and simple to use for file transfer over the TCP/IP and
therefore over the GPRS network.
As far as the AT commands list is concerned, the customer shall refer to the AT Commands
Reference Guide.
2.1.4 Email Client
SMTP and POP Application Layer protocol are available on the top of the TCP/IP protocol. This
permits sending and receiving Emails on your embedded device.
To get more information on system settings and AT commands available for email client please
consult the examples in the section 2.2 and AT Commands Reference Guide.
2.1.5 Known limitations
The implementation of the EASY GPRS feature has the following known limitations:
•
Only one socket can be opened at a time, no multiple socket connections can be made;
•
Only one connection request can be accepted at a time, subsequent requests will be silently
discarded.
•
Only the first GPRS context is associated with this feature;
It is taken for granted that external processor will be able to handle at least a limited v.24
implementation: RTS, CTS and, highly recommended, DCD lines; this because software flow control is
not applicable to the feature.
Due to the particularity of this feature, the flow control of both the directions uplink and downlink is
interlocked.
