I didn't have the chance to do any serious debugging, but it looks goofy as you have described. On one form, I am seeing blocks of code making no visual presentation whatsoever. Once the port opens, things go south very quickly. I delayed the opening until the last microsecond, updated and refreshed a textbox for status and started a transfer. No textbox update, transfer hangs the entire environment. I'm on 98SE at this minute...

>ouch! Well, it's nice to see I'm not totally crazy. Unfortunately, I had already used several database events.....I might be able to revert back, however. Sounds like a call to MS is in order (goodie, goodie).

>>VFP7 was my guess. I have a "sandbox" project in VFP6 where i keep 10-12 test forms for various serial configs and performance testing. On a lark early this AM, I fired up my factory fresh VFP7 and grabbed a sample matching your config. IT WOULD NOT WORK. Popped back into VFP6 and it worked dandy. Hmmmmmm...... Let's try another...... I gave up after 5. NONE OF THEM WORK IN VFP7. I am of no further use to you until I figure this one out. "No problem, just don't edit the menus or enable database events" my a**.
