Not sure I can ask this here. Please tell me where, if not here :-)
Recently got a Dynalink 128AE external isdn adapter connecting to sio0
(/dev/cuaa0).
I use it with user ppp in CURRENT of two days old. Just one line, not
128 bps, as my ISP does not do this. Below is the output of "show
physical", "show lcp" and "show hdlc".
Speed seems OK to me: between 8000 and 9000 bytes/sec when
downloading. Everything seems to work fine, but the kernel keeps
complaining about silo overflows. They are there all the time, but
especially when there is a lot of data coming in, e.g. when mail is
delivered by ISP or during cvsup. They are much worse on the PC the
adapter is on now than on another one, which runs 4.0-RELEASE, on
which I tried it as well. Is this because the serial port is not as
good or may it be SMP, which the other box hasn't, that causes it?
Dmesg:
sio0 at port 0x3f8-0x3ff irq 4 flags 0x10 on isa0
sio0: type 16550A
The IRQ is not shared. I also tried flags 0x20000 (from LINT), but the
adapter wasn't able to establish a proper connection. Connection died
by itself, without error messages and just a tiny number of bytes
recorded as exchanged.
Are some settings wrong maybe? I've tried to discover it all, but I
cannot find anything helpful for the overflows. If you need more
information about settings, I will gladly post them, here or on some
webpage.
Thanks!
