SPORT_SHOW_STATE (W*32, W*64)

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

Module: USE IFPORT

Syntax

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.
