I have some expenive (but oldish) hardware that needs to be controlled
from a PC serial port. Running the software on an old 233 MHz PC works
OK, but I can't tollerate the PC's lack of power.
However, running the same software, with the same operating systems
(tried XP Pro and 2000 Pro) on much newer PCs, I find the hardware
will not function.
I have some suspicion the serial ports on the newer machines might be
running at a speed too high for the oldish hardware, but I don't know
how to slow them down.
Any ideas?
