Oldie | Hi All,
with safety is these Topic already very old, but as Newbie .....
XP2c with Winxp/Win7. PC/Laptop over USB-Konverter of µController
How can The selected COM so read, the between COM empty and COM = 0 To discern is?
Beispieltext:
x$ = @ReadCom(COMadd%,1)
@ComError(COMadd%)
ifnot x$ = ""
a% = @ord(x$)
endif
self-evident are COM correctly initialized etc.
In Interpretermodus functions it correct, in Compilermodus becomes between Leerstring "" and Zero "0" with x$ not distinguished. evident becomes here the COMportbuffer constantly as "0" read, even if it is empty.
Sorry for such Anfängerfragerei,
BobCou |
