G'day Bill

 BG> Try again with your Courier set to S27=48 (disable V.42 detect
 BG> phase).

 PC> Already thought of that and tried it, no luck :-(

 BG> Bloody hell, that doesn't sound too clever then.  Have you tried
 BG> disabling the 3429 symbol rate, just in case the Simplemodem
 BG> (which uses a miserable 8-bit controller, BTW) has problems
 BG> similar to the Hayes Optima?

Yep tried that, no luck :-( 

 PC> also tried S27=32 to disable V42 and use MNP4, no luck

 BG> What have they done to the line; replaced it with wet string, or
 BG> what?

No idea but whatever it was it agreed with the Netcomm.

 PC> if i can remember them all i've also tried
 PC> S56=64  Disable V34
 PC> S54=128 Disable V.8 mode

 BG> Either of those will completely disable V.34.  Did V.FC work any
 BG> better?

It's a V.FC modem not V.34, i only tried disabling V.34 in case
something funky was happening in the negotiation stage.

 PC> S54=32  Disable 3429 symbol rate

 BG> That's the next one I'd have tried.  Incidentally, do you
 BG> normally run with V.8 CI tones disabled (S54=64) ?  Just a
 BG> thought...

I normally leave the CI tones on but have tried with the tones off as
well as V.8 mode off.

 PC> S51=64  Disable SREJ, The USR after call stats state that SREJ
 PC> is on after the failed connect even though i doubt the Simple
 PC> modem supports SREJ.

 BG> Dunno, some Rockwells (like the Viper) do actually support SREJ.

Remember this Simple modem is only a V.FC model, Did any V.FC modems
support SREJ?.

 PC> There may have been other settings i've tried Bill but have
 PC> forgotten about, If you can suggest anything else i'm willing to
 PC> try it. This problem is more of a "it won't beat me" problem
 PC> than anything serious as the Netcomm does the mail poll and it
 PC> seems to work without problem.

 BG> Bloody hell, you've tried just about everything.  About the only
 BG> thing left is your trellis coding.  Have you tried disabling
 BG> 64-State trellis with S55=8 ?

I have a feeling i've tried that too but in case i haven't i'll try it
again later as the computer with the USR attached isn't running at the
moment.

 BG> And yes, I'm REALLY clutching at straws now.  :)

 PC> BTW if i force V32bis with the USR it connects just fine with
 PC> V42/V42bis etc.

 BG> Now that's _really_ weird, as V.34 should theoretically be
 BG> superior to V.32bis at the same 14k4 class link rates.  What's
 BG> the Courier's S/N ratio like?

Can't remember at the moment but when i try with 64-state trellis
disabled i'll do a stats dump and post it.

We could always just put it down as a "Strange but True" thing. :-)
