Now that I have my system up, I'm trying to SLIP to my provider.  I have 
a copy of the SLIP document from the web; however, it is not working.

When I type:
   %cu -l /dev/tty00 -s 19200

it says that I connected, but I cannot type any 'at' commands.  The only 
commands I can do are the ~ commands.

My modem is in the modem port, and is a Supra FAX Modem at 14.4kb.

Clues?
