Is there a program like telnet, but driven by a script?

[Hugh Fader]

I need to duplicate UNIX-to-UNIX rsh functionality going UNIX-to-VMS.
I am running a Sun Sparcstation and can communicate with the VAX using
telnet and ftp via an ULTRIX gateway (the VAX only runs DECNET). One
solution to my problem would be a telnet-like program which accepts a
script containing expect/send pairs much like UUCP and some PC
communications programs. Does such a program exist?

I would also appreciate any suggestions of alternate solutions.

Thanks in advance.
