Summary: Don't put all that in the L.sys file

Writing the modem dialer in C has many advantages over L.sys chat scripts,
acucap entries, and Dialers chat scripts: you can parse multiple responses
from the modem; you can provide detailed logs of modem failures; call progress
monitoring can be supported; timeouts can be finely controlled. The dialers
facility in the next release of 4.3BSD UUCP will provide both the equivalent
of the HDB dialers scripts, and the ability for binary-only sites to add
C-coded dialers. That's the best of all worlds.

This is usable only if you have a small number of sites in your L.sys file (we
have 178, and some sites have over a thousand) and if you only have one modem
(we have six, including four incompatible types that could not be dialed from
the same expect/send script).
