•
The TCP/IP stack of TC63i supports using several service profiles at the same time, provided all of
them are running on the same connection profile. For example, it is possible to download files
from an FTP server, while sending and receiving emails at the same time.
•
GPRS connections established over the Dial-Up Network do not use the embedded TCP/IP stack of
TC63i and can be active at the same time. This allows the user to have two parallel GPRS
connections: for example, for sending or receiving emails over a GPRS connection enabled by the
TCP/IP stack while, at the same time, surfing the Internet over a Dial-Up Network GPRS
connection.
Address notation
Server addresses must be provided as IP addresses in standard 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").
Inactivity timeouts
Inactivity timeouts are not part of the Internet AT command functionality implemented in the
modem and, if desired, are the responsibility of the host application. It is recommended that the
host application validates URCs and AT command responses and reacts adequately, for example by
sending a close message or starting a timer.
