E.9 SPORT Routines (WNT, W9*)

SPORT routines help you do basic input and output to serial ports. To use a SPORT routine, add the following statement to the program unit containing the routine:

USE DFLIB

Table E-9 summarizes SPORT routines.

Name  Description 
SPORT_CANCEL_IO  Cancels any I/O in progress to the specified port. 
SPORT_CONNECT  Establishes the connection to a serial port. 
SPORT_GET_HANDLE  Returns the WIN32 handle associated with the communications port.  
SPORT_GET_STATE  Returns the baud rate, parity, data bits setting, and stop bits setting of the communications port.  
SPORT_GET_TIMEOUTS  Returns the user selectable timeouts for the serial port.  
SPORT_PEEK_DATA  Returns information about the availability of input data.  
SPORT_PEEK_LINE  Returns information about the availability of input records.  
SPORT_PURGE  Executes a purge function on the specified port.  
SPORT_READ_DATA  Reads available data from the port specified.  
SPORT_READ_LINE  Reads a record from the port specified.  
SPORT_RELEASE  Releases a serial port that has previously been connected.  
SPORT_SET_STATE  Sets the baud rate, parity, data bits setting, and stop bits setting of the communications port.  
SPORT_SET_TIMEOUTS  Sets the user selectable timeouts for the serial port.  
SPORT_SHOW_STATE  Displays the state of a port.  
SPORT_SPECIAL_FUNC  Executes a communications function on a specified port.  
SPORT_WRITE_DATA  Outputs data to a specified port.  
SPORT_WRITE_LINE  Outputs data to a specified port and follows it with a record terminator.
