2.6 Keyboard interface
!
Warning :
This interface is not FULLY available with AT commands :
description). This code has then to be processed by the application.
An AT command allows to get the input key code (see +CMER command
This interface provides 10 connections : 5 rows (R0 to R4) and 5 columns (C0
to C4).
The scanning is a digital one , and the debouncing is done in the WISMO Quik
Q24x6 Series. No discrete components like R,C (Resistor, Capacitor) are
needed.

2.7 Main serial link (UART1)
A flexible 6 wires 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), Clear To Send (CT106/CTS), Data Terminal Ready (CT108-2/DTR)
and Data Set Ready (CT107/DSR).
The set of RS232 signals can be required for GSM DATA services application
and is generated by the general purpose I/O provided by the Q24x6 series.
The 2 additional signals are Data Carrier Detect (CT109/DCD) and Ring
Indicator (CT125/RI).
