5.12.3.1 Plain Serial Interface
Scenario: A device is connected to ASC0 (refer to Section 4.2.4 ). The Java application must
handle data input and output streams. A simple Java application (with only one thread) which
loops incoming data directly to output, reaches data rates up to 180kbit/s. Test conditions:
hardware flow control enabled ( and ), 8N1, and baud rate on ASC0 set to
230kbaud (
→ theoretical maximum: 184kbit/s net data rate).

5.12.3.2 Voice Call in Parallel
Same scenario as in Section 5.12.3.1 , but with a voice call added. The application reflects
incoming data directly to output and, additionally, handles an incoming voice call. The data
rates are also up to 180kbit/s. Test conditions: same as in
Section 5.12.3.1 .

5.12.3.3 Scenarios with GPRS/EGDE Connection
The biggest challenges to the module performance are setting up a GPRS/EDGE connection,
receiving data on javax.microedition.io interfaces and sending or receiving the data on the
RS232 API with the help of a Java application.
