kppp error 16

[Chris Harris <chris harris cwfi co fk>]

I have a laptop installation RH7.3 KDE3.0.3.

When I try to dial a connection using kppp it fails with error 16, which 
according to the man page is " The link was terminated by the modem hanging 
up". I agree that the modem hanging up would cause the link to terminate.

Problem is that I have the same setup on a desktop machine, which works fine. 
The modem in the laptop is a PCMCIA, 56kflex compatible one.
ATI says FM560 Ver 3.01 V.90 (VER 1.14 TBR21 V.2) ERROR

 It worked under a previous installation of RH 7.2, but I didn't set that up 
and the person who did is unavailable. 

>From what I can find on the net the PCMCIA drivers and pppd are up to date.
There is a ethernet connection, which works fine. Can these exist together?

Is this a laptop/pcmcia problem, or a pppd / kppp problem? Or something else, 
All suggestions gratefully received.

Thanks 
Chris


P.S. The laptop is a CLEVO 2700T

Thanks Chris
