3.7 Main Serial Link (UART1)

A flexible 6-wire serial interface is available, complies with V24 protocol signaling,

but not with V28 (electrical interface) due to a 2.8-Volt interface.

The signals are as follows:

•  TX data (CT103/TX)
•  RX data (CT104/RX)
•  Request To Send (~CT105/RTS)
•  Clear To Send (~CT106/CTS)
•  Data Terminal Ready (~CT108-2/DTR)
•  Data Set Ready (~CT107/DSR).

The set of RS-232 signals may be required for GSM DATA services application and is
generated by the General Purpose I/O provided by the Wireless CPU Quik Q2687.

The two additional signals are:

• Data Carrier Detect (~CT109/DCD) and
• Ring Indicator (CT125/RI).
