Hi,

I am trying to read out a multimeter with Visual Basic 3.0 but I allways
get
an IO-Error.
So I wrote the small program below for DOS QBasic to test out wether the 
multimeter is out of order or my knowledge to small...

OPEN "com2:1200,N,7,2,RS,CS,DS,CD" FOR RANDOM AS #2
A$ = "D"
PRINT #2, A$;
in$ = INPUT$(14, #2)
PRINT in$;
PRINT "hallo"
CLOSE #2
REM PRINT #2, A$;

Well, it was my knowledge - It worked fine!!
Now my problem is simply to transfer this to VB...
I think the COM-Parameters in the first line are essential.
How do I "tell" VB to use this parmeters?
To set up the Port under Win95 had no effect.

I would be very glad if someone knows an answer!

Please reply also to pruemper@mailer.uni-marburg.de 
thanks!

Claus
