Serial port control information 
This is a string of 4 or 5 items, separated by dash:
  • nBaudRate 

Defines serial port baudrate. Possible values are: 110, 300, 600, 1200, 2400, 4800, 9600, 14400, 19200, 38400, 56000, 57600, 115200, 128000 and 256000. By default, 110 value is taken.

  • nDataLength

Defines data lengths in a packet. Possible values are: 5, 6, 7 and 8. Default value is 7 bits.

  • cParity

Defines parity is one of the following values: (E)ven, (O)dd, (M)ark, (S)pace, or (N)one. By default (N)one is taken.

  • nStopBits

Defines a number of stop bits. Possible values are: "1", "1,5" and "2". Default value is "1".

  • cHandflow

Defines flow control value. Possible values are: Hardware (P), Xon/Xoff (X) and None. Default value is None.

Serial/modem control lines state.

  • RTS - Request to Send line indicator
  • CTS - Clear to Send line indicator
  • DSR - Data Send Ready line indicator
  • DCD - Data Carrier Detect line indicator
  • DTR - Data Terminal Ready line indicator
  • RI - Ring line indicator

The gray circle stands for undetermined state. The red circle stands for low line level and green circle stands for high line level.
