Agreed. Even on a 56Kbps connection it's going to give you
grief...

Nope... Check that you have V.34 capable modems on both ends,
and then check that your V.34 connection is established. Also, make
sure that hardware flow control is functioning... You have to give
pppd the crtscts and modem options, ie:
/usr/lib/ppp/pppd /dev/<whatever> 38400 crtscts modem lock <localip>:<remoteip>
Flow control is a big concern... Without that, you're up the
creek... And if you've seen Niagara Falls, you'd know what I mean...

Assuredly...

Well, if they are getting FR 56, then it probably will fix the
problem... I just have doubts in the fact that the administration
can't get a simple PPP link up that they'd be able to handle the rest
of the network.

Why? V.34 modems use compression, and most IP traffic is
compressable data... I find that with WWW pages and telnets that a
28.8 Modem where the machines on each end are talking to the modems at
115.2Kbps and hardware flow control is configured propperly I often
exceed the speed of 56Kbps.
Try sending a long text file with Zmodem over a V.34
connection and look at the cps... Then, go figure... I admit that
one FTP transfer of a compressed file will throw a wrench in the
gears, but hey... Then you're at 28.8 for those packets...

The only thing I can say is that PPP with 1.1.75 1.1.74, and
below has worked for me flawlessly over the following correctly
configured mediums:
o Null Modem
o 28.8 V.34 and V.FC modems.
o Telebit WorldBlazer PEP
o Wireless 56Kbps radio over a distance of 10 miles. (Yes,
full duplex.)
And I'm certain that with my experience I could probably make
it fly over two tin cans and a string... ;-)

I say we boycott them... I sure am...
Quote:>Can you say "no repeat customers"? I know I can.
I have never bought a BOCA modem... Mainly because of the
constant grief I hear about their products from people I tell, "Don't
buy the BOCA..." And then I usually hear, "Oh, but look at the
price!" But then again, these are the same people who go out and buy
the $15.99 ratchet set to rebuild the engine in their 1978 Chevy
Impala... ;-)
