Maybe you could be more specific about what you want the settings to
accomplish.  If everybody is coming *in* to the BSDI system, then
obviously you don't want a SET LINE command in your .kermrc file.
And you can also make Kermit start up a lot faster by removing all of the
local-mode-only items from it -- dialing and services directory setup, 
etc.  This can be done without editing the file by including the -R
(uppercase) (= "remote only") command-line option.  You can do this with
an alias, such as:

  alias kermit="kermit -R"

As far as file transfer goes, you can increase the default packet and
window sizes to the maximum levels that seem to be safe for your
equipment.  Some trial and error will be necessary -- no single collection
of settings applies to every situation.  If it did, we would use it!
