RTS / CTS hardware protocol
- MicroBar acts as a standard terminal and manages the RTS/CTS lines when configured
- CTS is tested before transmission of each character - data is only transmitted when CTS is
activated (high)
- if CTS not used by the host system, MicroBar keeps the level high
- RTS is activated (high) before data is transmitted
- RTS is deactivated (low) when message transmission is completed after the specified timeout
- "beep after transmission" if good read ("beep before transmission" also possible - see section 7
"Operating settings")
- 6 error beeps if no response from the host system before end of timeout
- RTS/CTS exclusive with ENQ/ACK/NAK and XON/XOFF
