Display problems

Hi,
I'am using the BS-2p40 together with a BPI-216 LCD-display. When is
start running the code (see bellow). I can see sometimes a test -
message. Only after 1 second, the display shows only some weird
characters. I've checked the dip-switches on the back, and the seemed
in the good position. I've also tested the same application with
another display, so I dont think that's the problem. Is there maybe
something wrong with my code ?
Thanks
Hans

Your code is wrong. Write:
N9600 con 16468 (or the HEX number)For Hans.
I con 254
clr con 1
L1 con 128
L2 con 192
serout 0, N9600, [noparse][[/noparse]I, clr]
serout 0, N9600, [noparse][[/noparse]L1, "Hello"]
serout 0, N9600, [noparse][[/noparse]L2, "Goodbye"]
The test message appears when Vdd is applied to the display serial pin at
startup.

You are ignoring Line 2 - L2 con 192. The test message will come up if Vcc
is supplied at start up.

Hello Hans,
I don't know if this applies to your setup (Not
familiar with that particular display)...But a few of
the serial displays I have used display a revision
message, or something else during initialization. If
you're using the PIC-N-LCD it displays a revision
message as well...Hope this helps. By the way, if
that is the case, you should still see it when you
power up the LCD by itself.
