Looks like your modem is not really detected by linux.  The "connected" 
message from cu only means that it was able to access /dev/ttyS1 device, but 
the fact that your commands are not echoed means your modem is not detected.  
Most pnp modems need isapnptools to work, unless there is a way to get it back 
into "legacy" mode. Install isapnptools package, and take a look at 
/usr/doc/isapnptools/INSTALL.
