If APO's modem pool is to become a reliable backup mechanism for observers,
it needs some work.

Presently it only supports uncompressed SLIP, which is a waste of bandwidth
and also hard on Mac users (there is not good free SLIP software). Support
of PPP would be a huge help and is probably very easy to implement on the
APO terminal servers (our local phys/astro computing center has done it and
can offer advice if necessary).

Also, for reliable connections it is worth making sure APO has
internet-service-provider quality modems. (USR Courier V.Everything modems,
for instance, are very high quality and only cost $300.) Observing time is
too precious to play around with anything less.
