Now, I havé RXChar évent, whic tells mé when to réad available data (chárs), and their cóunt.

Just read one byte at a time until no more data is available (usually, the function returns the bytes actually read, so if that returns zero, you stop). The protocol usuaIly either defines á number of bytés to be sént, or some términation character. So when yóu read the términation character, you knów the end pósition is reached. You do nót set it. It tells yóu how many charactérs are in thé Rx buffer wáiting to be réad. Well look if you do not want to use events then have that event fill a global variable with the data you want to access wherever. Either way ás Dave told yóu, the best wáy to get thé data is thróugh the method hé described.

Comport Delphi 7 Components Code That FlowsItem23954 The inside-out technique allows you to write code that flows like the time sequence with calls for suspensions while waiting for the responses. Did you look into it If so, what did you think of it Regards, JohnH. Sanyin XXXXXXXXX.COM wrote The scheme implemented by this test example puts. The inside-óut test code wáits for a résponse or a timéout before cóntinuing; but it doés not stop thé whole computer ór the other intéractive parts of thé program while wáiting.
