Hello all,
I have a problem with event service routine ! I implement =
PCOMM.DLL(MOXA) library contributed from Kondor Attila and
communication =
with serial port work very well, but his pcomm.ew lack any event
service =
rutine . Down at bottom is help for C++ for creating event
service =
routine in case when terminator character is received. =20
After I successfully register event service with :
sio_term_irq_=3Ddefine_c_func(Pcomm,"sio_term_irq",{C_INT,C_INT,C_INT},
=
C_INT)
global function sio_term_irq( integer port,atom TermIrq, atom code)
ret=3Dc_func(sio_term_irq_,{port,TermIrq,code})
if ret=3DSIO_BADPORT then
warnErr("Port is not opened in advance")
end if
if ret=3DSIO_WIN32FAIL then
warnErr("Calling Win32 function failed")
end if
if ret=3DSIO_BADPARM then
warnErr("Bad parameter")
end if
return ret
end function
sci_rup=3Dsio_term_irq( 1,??? , 59)
??? any number form 1 to 50
and return 0(SIO_OK) which mean event service enabled, after if =
terminator character is received programm crash with message
"EXW.EXE =
generate errors . . . ". After that I don't now how to handle ( =
possible with call_back but I don't now HOW ...)
Language Syntax
C/C++ int WINAPI sio_term_irq(int port, VOID (CALLBACK
*func)(int port), =
char code)
Argument:
port =3D COM port number
func =3D event service routine entry
If the func is NULL, it will disable this routine.
code =3D terminator code
Return:
SIO_OK OK
SIO_BADPORT Port is not opened in advance
SIO_WIN32FAIL Calling Win32 function failed
Call GetLastError to get the error code
Example:
C/C++
/* Define event service routine */
/* Recommend to declare this function as global function */
VOID CALLBACK TermIrq(int port)
{
}
/* Enable event service routine */
ret =3D sio_term_irq( 2, TermIrq, 'A');
if (ret !=3D SIO_OK) {
/* Fail */
}
/* After event service routine enabled, TermIrq() will be
activated =
whenever terminator character is received. */
/* Disable event service routine */
ret =3D sio_term_irq( 2, NULL, 0 );
