I've no experience with serial modems, but having read the man pages I 
believe your remote(5) line is incorrect.

sio0|com1:dv=/dev/cuad0:br#115200:pa=none:

sets system names sio0 and com1, then you try to execute tip to connect 
to cuad0. Is there an entry for cuad0 in your /etc/remote? I'm confused 
as to why tip is returning 'unknown host tip0' however.

Give `tip -v sio0` a shot, or change the system names in your 
/etc/remote line
