# SPORT_SHOW_STATE (W*S)

Serial Port I/O Function: Displays the state of a port to standard output.

## Module

USE IFPORT

result = SPORT_SHOW_STATE (port,level)

port | (Input) Integer. The port number.
level | (Input) Integer. Controls the level of detail displayed as follows:
0 | Basic one line display
1 | Basic information
2 | Add modem signal control flow information
3 | Add XON/XOFF information
4 | Add event character information
11 | Add timeout information
901 | Add debug information

## Results

The result type is INTEGER(4). The result is zero if successful; otherwise, a Windows* error value.

### Note

This routine must not be used when any I/O is pending. Since a read operation is always pending after any I/O has been started, you must first call SPORT_CANCEL_IO before port parameters can be changed.

## Example

    USE IFPORT
    INTEGER(4) iresult
    iresult =  SPORT_SHOW_STATE( 2, 0 )
    END
