Yes, you're right. Thanks for pointing this out. I have changed this to
$KERMIT -C "SET EXIT WARNING OFF,REMOTE $1,QUIT"
and quoted the places where hp48_cmd is called. I think this is easier 
to understand. (And I don't like $*.)

[Offtopic:] Can you tell me a situation where you use $*?

Well, I think that it is not easy to do overquoting the wrong way. The 
approach that I like is to quote everything that I consider to be a 
string. This includes arguments to `case'.
