Hserin amount

I've found some threads that confirm the problem I'm having but none that provide a resolution.

Why doesn't this work:

HSERIN 1, [STR DAT\800\"@"]

But this does?

HSERIN 1, [STR DAT\255\"@"]

Is the maximum input for an array 255? The only way I can make it work right now is:

HSERIN 1, [STR DAT1\255\"@", STR DAT2\255\"@", STR DAT3\255\"@", STR DAT4\255\"@"]

I use this code to receive string longer then 255 chars

Code:

---

FOR i=0 TO 799
HSEERIN 1, TimeOutLabel,[Chr] ' get char
IF Chr="@" THEN
 GOTO Done 'End of data
ELSE
 DAT[i]=Chr ' put char in array
ENDIF
NEXT i
Done:
DAT[i]=0 'End of string

Make sure you declare variables that will be over 255 as words, also assume you have a typo in the above code "HSEERIN".

Because the serial buffer is one byte. HSERIN looks at the one byte buffer received.
The idea is to cycle the rest of your program between bytes.
