I'm running BIT on NT4.0 on a custom-made PC-board.
COM2 & 4 throughput is over 1000 times more than COMs 5,6,7 throughput (when running tests simultaneously at the same BAUD).
COM 1,2,3,4 came built in to the PC-card that is at the heart of the board. COMs 5,6,7,8 were added later by someone else.
Does this indicate some kind of fault on COMs 5,6,7?
I assume that for a given baud rate, the throughput should be approx the same for any port?
FYI I am seeing:
COM2,COM4 both have similar throughput (1800 or so Bytes/sec @ 115200)
COM5 1000 times less (throughput of 1 to 4 Bytes/sec (@ 115200, during same simultaneous test session))
FYI it also says DSR is always low, but that might just be because it hasn't been wired through.
The CPU usage and memory usage as reported by task manager are fine.
