Die folgende Frage habe ich (bisher leider erfolglos) in
comp.unix.unixware.misc gepostet. Are there any hints?
I'm running the following environment on my 486/50:
cpu: 486/50
com2: 16550 fifo
modem/TA: ZyXEL Elite 2864I with firmware 1.09 for DSS1
os: Onsite Unix SVR4.2 Version 1.0 (based on USL)
asyc-driver: sas-1.25 with some fixes
PPP-sw: pppd-0.85
fax-sw: HylaFAX v3.0pl1 (BTW: works also fine)
DTE-speeds: 38400 for fax and dial-in, 115.200 for dial-out (PPP)
usage: 24 hours ready for incoming calls, ~4-6 hours PPP
CONNECT: 24.000-28.800, less then 1 line drop per week
ISDN 64000/115200 X.75
I'm using the 2864I with ISDN X.75 PPP to my ISP. This works fine
and w/o any problems at DTE speed 115.200.
The used AT-cmd's are:
AT&FE0
AT&O2
ATB00
ATD........
There are no problems. Some days ago I ftp'ed a ~7MB file from
my ISP with 4.6 kbps.
In our company we've a ISDN-router (BANZAI!). The BANZAI! also
speaks PPP. After fixing some negotiating problems the link is
now up and running and I can telnet, ftp (small files), ...
The 2864I AT-cmd's are:
AT&FE0
AT&O1
ATB40 <*** async-to-sync-PPP converter)
AT&K00 <*** disable V.42bis
AT&H3
ATD.......
The bad news are:
If I want to ftp-put a large (say 1MB) file the connection freezes
with the follwing symptoms:
- sending "put filename" scrolls very slow one line up in my xterm
- the ftp-transfer and all other (e.g. telnet) connections are stopping
after 1-2 seconds (they don't drop but are w/o traffic);
- no more then ~6KB are transfered to the remote ftp-server disk;
- killing the pppd with kill(1) gives this panic:
PANIC type 0x0000000E
eax: 0 ebx: 0 ecx: 27 edx: d0120ea0 efl: 10286 ds: 160
esi: 0 edi: d139cc40 esp: e0000d34 ebp: d016d07c regset: 0 es: 160
sasintr+3e62: movl(%eax),%eax
KDB>>
- if the file is compressed with gzip, the transfer works for
2-3 minutes and ~600 KB are transfered;
[BTW: the transfer freezes in the same moment I've opened another xterm
but this may be meaningless];
Where to start debugging? sas-driver? ppp-asyc driver? other places?
BANZAI!-kit ?
Is the 115.200 fast enough for the ISDN rate (64kbit)?
Should I go and buy a I/O card with hardware 460.800 speed.
Thanks in advance for any hints.
