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
