In order to run an analogue to digital convertor module from a serial
port, I want to send a byte from the port every 10 ms.  This sets the
sampling rate, so the accuracy of the interval is very important.  The
VB Programmer's Guide mentions BUILT IN POTENTIAL FOR ERROR in timer controls, a great
euphemism if ever I heard one.  Can I get good precision from VB, or do
I need to work in C (please not!) or C++(worse still) or write a VxD
(I'd rather sell life insurance)?

All ideas gratefully received: unlimited fame more or less guaranteed
for useful ones.  Thanks in advance, O Wise Ones.
