Yeah I was trying for the 230000 I am isdn that was the whole
purpose of the 16650 to increase thoughput.
jkh mention that freebsd could handle 230 no problem just the 115000
16550 was the restriction. it runs in windows 95 fine on the 230000
settings. If I where able to get no speed change I would stay at
115000. Are you also isdn?
A you COULD fix it by recompiling the kernel with the HZ value set to 200
intead of 100. or you could do what we did which is to get a uart with 32
byte fifo's instead of 16.
the trouble is that the serial devices are not REALLY
interrupt driven, but run by the clock (it's a long story).
16 bytes at 230K is < 10mSec (the Hz ia 100Hz)
