If you need something slightly more robust, you may want to look
at lang/expect, which uses send/expect sequences similar to kermit
and uucp, but with more powerful options:

man expect(1):

 | Expect is a program that "talks" to other interactive programs according to a
 | script.  Following the script, Expect knows what can be expected from a program and
 | what the correct response should be.  An interpreted language provides branching and
 | high-level control structures to direct the dialogue.  In addition, the user can
 | take control and interact directly when desired, afterward returning control to the
 | script.

 cheers, Jamie
