That's it. Thanks:)
It seems that ``shell'' doesn't behave as described in the manpage for
ppp:
shell|! [command]
If command is not specified a shell is invoked according to
the SHELL environment variable. Otherwise, the given command
is executed. Word replacement is done in the same way as for
the ``!bg'' command as described above.
However, if I add
isp:
shell
to /etc/ppp/ppp.linkup, I get
marder-1:/usr/mark{58}% ppp
Working in interactive mode

Hmm, I'll try and look into this and, if necessary, update the manual
page.
Brian, are you reading this? If so, do you have any comments?
