ASC0, an Asynchronous Serial Controller, is a 9-wire serial interface. It is described in 

. With-

out a running Java application the module can be controlled by sending AT commands over
ASC0. Furthermore, ASC0 is designed for transferring files from the development PC to the
module. When a Java application is started, ASC0 can be used as an RS-232 port or/and Sys-
tem.out. Refer to 

 for details. 

There are ten I/O pins that can be configured for general purpose I/O. One pin can be config-
ured as a pulse counter. All lines can be accessed under Java by AT commands or a Java API.
See 

 for information about usage and startup behavior.

There are two analogue input lines and one analogue output line. They are accessed by  AT
commands. See 

 for details.

The TC65 Terminal does not feature DAC interface.

ASC1 is the second serial interface on the module. This is a 4-pin interface (RX, TX, RTS,
CTS). It can be used as a second AT interface when a Java application is not running or by a
running Java application as RS-232 port or/and System.out.

The TC65 Terminal and products with GPS do not feature ASC1.

The ME has a seven-line serial interface with one input data clock line and input/output data
and frame lines to support the DAI. Refer to 

 and 

 for more information. 

TC65 Terminal does not feature a DAI interface.

There is a 4 line serial interface which can be used as I2C or SPI interface. It is described in

. The AT^SSPI AT command configures and drives this interface.  For details see
