Hi,

I'm running ver 2.0 and having terible problems with silo
overflows. Here's an excerpt from /var/adm/messages...


Feb 18 19:33:50 willie kernel: sio0: 2 more silo overflows (total 104)
Feb 18 19:34:13 willie kernel: sio0: 3 more silo overflows (total 107)
Feb 18 19:35:00 willie kernel: sio0: 1 more silo overflow (total 108)

Quite often, the system reboots.

Here's what I'm working with ..
Feb 18 19:06:27 willie kernel: CPU: i486DX (486-class CPU)  Id = 0x435  Origin =
 "GenuineIntel"
Feb 18 19:06:27 willie kernel: real memory  = 16384000 (4000 pages)
Feb 18 19:06:27 willie kernel: avail memory = 14745600 (3600 pages)
[stuff deleted]
Feb 18 19:06:27 willie kernel: sio0 at 0x3f8-0x3ff irq 4 on isa
Feb 18 19:06:27 willie kernel: sio0: type 16550A

I'm using an intel 14,400 v.42 faxmodem. I am using kermit as a
dialer. I have done alot of experimentation with changing flow control
on both the software and the hardware (with AT commands), and speed. I
get overflows at 9600 baud as quickly as I get them at 57,600.

I'm at a loss. It's been impossible for me to sup, or in fact get any
real work done with this problem. Does anybody have any ideas, or is
anyone experiencing similar problems?

Thanks,
Willie
