connect string, a return character will result in a login prompt from
my ISP. No amount of banging on the keyboard has had any effect. I
cannot tell, at this point, whether thats because nothing is going
upstream, or nothing is coming back, nor where the I/O is being
stopped.
Thats quite a jump in kernel versions. I suspect there have been
several changes to the module involved. Maybe you should "binary-search"
down to the first kernel that breaks things.
Unless I misunderstand what youre suggesting, that would be a monumental
undertaking. The only "delta" I have between RH8 and FC3 is FC2, and it
was also problematic, although to a very slightly lesser degree (i.e.,
kppp worked). But more importantly, I have only the one box here. I wish I
had a test box which I could use to try out different installs, but even
with the dual-boot configuration, this machine doesnt serve that purpose.
And, being on dialup, grabbing distros is at best, a pain.
By the way, what module is getting loaded to support the Belkin F5U103
adapter? It should be the belkin_sa module, per the source code. Your
post caught my eye because I occasionally (very successfully) use a
Belkin F5U109 RS232/USB adapter in a similar manner (i.e. for modem use,
but under kernel 2.4.22, Slackware 9.1) but it uses a different kernel
module (mct_u232), so unfortunately, I cannot really comment any
further on your specific problem.

Since I have 2.4.22 and 2.6.1 source code hanging around on this
machine, I did a quick diff on the belkin_sa.c file. There are
several changes just between those 2 kernel releases, so I think my
"binary search" advice applies, unless someone else more familiar with
that module speaks up first. In fact, this problem might get better
replies over on the Linux-USB-Devel mailing list.
Well, my past experience is that denizens of Devel also monitor users. If
thats not true on this list, then Ill check my assumptions, and try next
door.
Also, Ill add that what I wasnt sure about earlier is the case. There
are two USB drivers being loaded. From dmesg:

My recollection for past kernel builds is that you choose one or the
other. But of course 2.6 brings many changes.
And, since FC3 brings many changes from RH8, Im still coming to grips
with how to make it behave "my" way.
