I have a VFP9 app running on WinXP That utilizes MSCOMM32
to drive the customer display for a POS cash register.
The display is connected to COM1 and works as expected
except at random intervals will cause a "program not responding" hourglass to appear. After 15-60 seconds the
program resumes normally. I have found that I can induce
this behavior by rapidlly scanning 30 or 40 items which means output is going to the customer display 2 or three
times per second.
Has anyone seen this behavior or suspect what causes it.
