Right now I'm using netcfg.  No problems using the Sportster with /dev/modem 
linked
to /dev/cua0.  This obviously bypasses the connect script, anyway, because the
connect script you see below (/etc/ppp/connect) has the ISDN connect telephone 
number, and I just connected using the analog number, which ends in 8211.  
So I'm not sure if this script is even getting called.  Are you familiar with 
Red Hat's netcfg?  Or do you see problems with this script?  (I suppose the
modem init string does not apply to the TA, but I've no idea what to replace
it with.)

TIA,

Lance
