To all interested:
Regarding the specifics of my SerClose problem
(it hangs if using hardware handshake and
nothing is plugged into the port). I've stripped
things down, and the code snippet below
displays the problem ... it's essentially pulled
straight from the online documentation. Note
that no errors are ever returned (my actual
code tests 'em).
// demonstration of my SerClose problem ....
Err e;
SerSettingsType sstSetup;
extern UInt SerialRefNum;
e= SerOpen(SerialRefNum,0,9600);
e= SerGetSettings(SerialRefNum, &sstSetup );
sstSetup.baudRate= 9600;
sstSetup.flags= serSettingsFlagBitsPerChar8 |
serSettingsFlagStopBits1 |
serSettingsFlagRTSAutoM |
serSettingsFlagCTSAutoM;
// NOTE: if the RTS and CTS flags are not ored in,
// then there is no problem with SerClose
sstSetup.ctsTimeout = (SysTicksPerSecond() / 2);
e = SerSetSettings (SerialRefNum, &sstSetup);
SerReceiveFlush (SerialRefNum, 100);
// write something
char buffer[]= "yippee, it works!";
ULong bytesWritten= SerSend
(SerialRefNum,(VoidPtr)buffer,StrLen(buffer),&e);
SerReceiveFlush (SerialRefNum, 100);
// changing settings here to have no hardware handshake
// won't work since SerSetSettings appears to hang then!
e = SerClose(SerialRefNum); // HANGS ME OUT TO DRY!
// alert never shows if something isn't plugged into the
// port ... plug something in and "pop" the alert comes
// up.
FrmCustomAlert(JustAnAlert,"","","");
Many thanks in advance to the kind soul who can crack this one.
Folks in the field are bumming since they have to reset if they
push the 'print' button when no printer is attached!
