Others have reported problems reading COM ports using fopen and fgets or
fread. They open the port and start reading but nothing ever arrives.
I have the same problem and discovered the following. There is an 8K
input buffer. Only after 8K bytes have arrived does fgets or fread see the
first.
How does one get around this feature (or bug)?
This is with php 5.0.2.2 on Windows XP.
