Talk Demonstration
This demonstration implements character level communication.
1. Connect two serial port terminal emulators (such as HyperTerminal) to the
RS-232 ports of a pair of Explorer 16 Development Boards.
2. Type your message in one of the terminal windows.
As soon as the Enter key is pressed (i.e., a CR character is sent), the message will be
transmitted via the modem interface, preceded by an 8-byte synchronization preamble,
and should be received by the second device and printed in the other terminal window.
The message buffer size is 80 characters. If the CR character does not appear, the
message will be transmitted after the 80th character has been received. Except for the
CR character, no other characters have any special meaning and everything that
appears at the serial port input, will eventually get transmitted via the modem output.
As there is a difference in transmitting speeds, the serial port being much faster than
the modem interface, care must be taken not to overflow the input. When the modem
is transmitting its current buffer, it silently ignores everything that it receives via the
serial port. The UART configuration for this demonstration is:
? 19200 bps
? 8-N-1
? No flow control
