IRP: Represents a counter of passed IRPs (Input/output Request Packets)

Read: Displays a number of bytes read from serial port

Written: Displays a number of bytes written to serial port

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 in 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.
