PetitModem is hard to get working. Make sure to choose the slowest speed, and the two way communication mode (duplex if I remember). Also make sure the settings on the computer and smile basic sides match. Packing and unpacking files is also fairly cryptic. If you have the special cable try plugging mic into headphone and headphone into mic. If not turn things up obnoxiously loud and hope.
