[Mark] and [Space] parity do not allow for error detection.
[None]  none
[Even]

[Space]  parity bit is always 0

Stop Bits [1]

Stop bits indicate the end of a serial data packet. (A start bit indicates the 

beginning.) The standard setting is 1 stop bit. Communication with slow 

devices may require more than 1 stop bit. Configuration options: [1] [2]

Flow Control [Hardware RTS/CTS]

Flow control can prevent data loss from buffer overflow. When sending data, 

if the receiving buffers are full, a “stop” signal can be sent to stop the data 

flow. Once the buffers are empty, a “start” signal can be sent to re-start the 

flow. Hardware flow control uses two wires to send start/stop signals. 

Configuration options: [None] [Hardware RTS/CTS]

Recorder Mode [Disabled]

With this mode enabled only text will be sent. This is to capture Terminal data. 

Configuration options: [Disabled] [Enabled]
