Hi
It seems that the z8530 hangs (?), receiving works, transmitting dont work..
:/
This happends after about 20 hours, anyway the 3-4 last times for me..
I�ve changed io-port, compiled the patched driver i found in the archive at
f6fbb,
i didn�t use the driver found in the kernel at all, and i use this as
module.
(replaced scc.c/.h in z8530drv-2.4c archive)
In the patched driver, when the watchdog founds that the TxInt dosn�t
changes,
then it reset the z8530 chip, and generates 1000 TxUnder to tell this.
(Thats why you whould see lots of TxUnder in my sccstat output..heh,
41 resets on scc1 and 2 resets on scc2)
Does anyone runs Baycom USCC>4 with Linux and dosn�t get this problem ?
This time it was scc0 and scc2 that stopped to transmitt, supricing enoth
dosn�t the watchdog _ever_ reset scc0, only scc1 and scc2..
Symptoms:
Status at port scc0 before i try to call someone up.

As you can see, the receiving works, but transmitting dosn�t.. :/
I includes here some more info from my system..
