Surprising... :-O
I get the point. But I do not think I have reached any resource limits when this happens. I know that is hard to judge. And I could be very wrong.
Yep. But it is indeed surprising that this could happen with current hardware. I wasn't even aware that it could happen. You see, if a plain 8086 could cope (barely) at 115000, a pentium should not even cough. It might be worth a bugzilla report... Another idea. There are some settings in the kernel about how fast is the task switcher clock and how interruptible are some tasks, and real time settings. Playing with that could help. I have found that some times, when a task is busy (mozilla!) the response to the keyboard is sluggish, might be related to your problem. I have been playing a little with those settings, but I'm not learned enough on linux kernels to recommend anything conclusive.
If hardware handshaking is impossible, revert to software handshake (much slower, chars have to be sent back)
But the software handshake must require that the driver is getting called in time, no?
Exactly; in your case it wouldn't be much use, or none at all. Mmmm... - -- Cheers, Carlos E.
