Communications Protocol
The protocol is 8 data bits, 1 stop bit, and no parity. Handshaking is DIP-switch-selectable,
either or RTS/CTS or XON/XOFF (parameter n4).
Baud: 2 400, 4 800, 9 600, 19 200, 38 400, 57 600, and 115 200 bits/s
Flow control: None, Xon / Xoff, or Hardware
Data bits: 8 (fixed)
Stop bits: 1 (fixed)
Parity: None, Odd, or Even
Default settings: 115200 bits/s, 8-bits, No parity, 1 stop bit, and hardware flow control.
Note • Use RTS/CTS hardware handshake (parameter n4=2) and ACK/NAK + error code
enabled (parameter n5=0).
