Or... if you want to automate the interface I'd recommend the Net::Telnet module for perl. Despite the name it can work with any filehandle, and supports various methods for sending commands and receiving (and waiting for) responses. I've also used cu (part of the uucp distribution) under perl's Expect module to do this sort of thing, where cu handles the comm channel and expect the timeouts and automating the interactive stuff, but find Net::Telnet a simpler solution.
