Communications Protocol
The Encore 2 supports RTS/CTS (hardware) and XON/ XOFF handshaking protocols to synchronize with the host terminal. The handshaking protocol and the baud rate is programmable. The default communications parameters are:
Handshaking = RTS/CTS | Baud Rate = 9,600 |
Parity = None | Data Bits = 8 |
Stop Bits = 1 |
