Hi
I�m running Linux at our local BBS, kernel 2.0.35, it�s stable and nice.
But there is some problem with the z8530drv-2.4c, as you know, i�ll found
out
that in kernel 2.1.xxx thats more work done with z8530drv.
What does you recomend me to do?
1, Patch the 2.0.35 kernel with z8530drv-3.0-patch-2.0.35, and use 3.0
sccutils
2, Upgrade the system to run kernel 2.1.xxx
3, Continue to use z8530drv-2.4c, and wait for release of kernel 2.2
It seems that z8530drv-2.4c runs now, at least the 3 1k2 ports whe have,
the 9600bps port seems to going up and down, not the PTT problem here..hi,
but this port seems not to here sometimes.. ;)
This port generates _LOTS_ of interupts/rxerrors.

About 42 _millions_ of rxinterupts on 48 hours, and i�m the only one who
access this port,
Approx 243 rxinteruppts / sec , this is _bad_ thing.
Okay, the system dosn�t seems to slow down, but i can figure out how the
driver works hard.. :/
Hm.. allright, i�ll have this problem when i used 9k6/G3RUH modem on our
last MS-DOS box with
G8BPQ/F6FBB/KA9Q Nos, here i�ll used a simple AND to avoid this. (used DRSI
cards then)
(i.e: Don�t send any data if there is NO DCD from modem..)

DCD o----|---/

I�ll will made this HW mod to the 9600bps modem thats on Baycom USCC>4 also,
then i should get rid of this (stupid) problem also..
But, there is some code in scc.c thats �turns off� the receiver when this
modem
runs with �External clock� , shouldn�t this be a �soft� solution insted of
my HW patch?
Sometimes i�ll see the rxinterupts stop increasing, but at most it dont
stop..
BTW, is the development discontinued on the z8530drv thats found in 2.0.xx
kernels?
(i.e z8530drv-2.4c)
Whops, this was mutch more than i intended to write.. ;)
Okay, 73�s de Morgan / sm6tky es Happy new year to all of you.
