I'm having trouble interfaing with my modem. I've been using 

"cu -l /dev/tty00" 

(the modem is in the modem port -s speeds don't have any affect).

after it says "connected" as soon as I hit a single letter, it says "cu: 
write: Input/output error"

I'm using a global village platinum modem. Was I supposed to do something 
to set it up to use a modem first? Is it a problem with this type of modem?
