I'm using an FTDI245B (parallel) chip with the FTD2XX dll interface at the PC and I have a "response time" problem.
With a PC receiver in a tight loop, when I send data there is always the same perceptible pause (400 msec??) before it is received. I was expecting something more like 20-50 msec - i.e. apparently instant. (Note that this is with NO traffic from the PC to the FTDI device.)
As performance is not yet important I've got the problem on a back burner - but I'd appreciate anyone who has had a similar experience giving me a clue of where to look next!
Thanks in advance.
