Problem with VISA's Serial COM buffers

LV 5.1.1
WinNT 4.0

Hello. I hope somebody could explain me this things. I have been figuring
this one out for over a week why some of the data I'm expecting from the
serial port when is getting lost when I am reading it. I'm really expecting
a lot of data to handle and haven't seen this problem when I'm using VC++
(which means that the OS' serial buffers is not the one at fault here). I
already adjusted the buffer to 5024kb but still no use (compared to 1024kb
on VC++). So far, I still haven't tried to fully test my apps (which will
then read 48x the data I'm testing right now) which means that my labview
program will definitely cave in.

If you have any advice on how to solve this problem (making sure that all

data are read accordingly using VISA), please post it here.

Any help is greatly appreciated.

TIA,
John
