HWXmitComChar

  • 项目

This function transmits a single character.

BOOL HWXmitComChar(
  PVOID pContext,
  UCHAR ComChar 
);

Parameters

  • pContext
    [in] Pointer to a context structure returned by the HWInit function that contains implementation-specific data describing the hardware device.
  • ComChar
    [in] Specifies the character to transmit.

Return Values

TRUE indicates success. FALSE indicates failure.

Remarks

The lower layer transmits the character specified by HWXmitComChar as soon as possible, before any buffered data. HWXmitComChar is called by the user through the TransmitComChar function or by the upper layer, usually for XON/XOFF processing.

This function supports the implementation of the lower layers of serial port drivers.

Requirements

OS Versions: Windows CE 1.0 and later.
Header: Serhw.h.
