3.6 Main Serial Link (UART1)
A flexible 8-wire serial interface is available, complying with V24 protocol
signalling, but not with V28 (electrical interface) due to a 2.8 volts interface.
The signals are:
TX data (CT103/TX)
RX data (CT104/RX)
Request To Send (~CT105/RTS)
www.DataSheet4U.com
Clear To Send (~CT106/CTS)
Data Terminal Ready (~CT108-2/DTR)
Data Set Ready (~CT107/DSR).
Data Carrier Detect (~CT109/DCD)
Ring Indicator (CT125/RI).
