Has anyone out there tried throwing the "persist" option to pppd ?

>From "man pppd"
persist - Do not exit after a connection is terminated; instead try to
reopen the connection.

I don't _think_ this will have the desired affect, but it might. I have
very stable connections, and have it thrown in there somewhere, but then
again, I don't download that much from home, being that I have a fat,
underutilized connection at the office.
