Help, please....

I am trying to hook a modem up to my Sun 4/110 that is running SunOS 3.2 
and can't quite seem to get it to work.  The problem seems to be when
I enable logins to the port that the modem is hanging on.

Configuration:

o The modem is connected to serial port a.

o I turned off the software carrier in the kernel with the following mod:
	device          zs0 at obio ? csr 0xf1000000 flags 0 priority 3
  (I got desperate and was trying the modem on both ports).	

o I create a minor device that looks like:
	0 crw-rw-rw-  1 root      12, 128 Jun  8 15:09 cua

o I changed the ttys entry so that it looks like:
	1fttya

o This corresponds to my gettytab:
	f|std.1200|1200-baud:\
	        :fd#1:sp#1200:

o I have an entry in my /etc/remot that looks like:
	modema:\
	        :el=^D^U^C^S^Q^O:ie=$%:oe=^D:br#1200:dv=/dev/cua:

Now, when I try the command "tip modema", I get the following response:
	tip: /dev/cua: No such device or address
	all ports busy

So, I edited the ttys entry, it reads "0fttya", effectively disabling
the getty on that port.  Now I can tip just fine to the modem, but the
login is disabled.  

Has anyone encountered anything like this?  Anyone see any blatent errors?

Thanks for any help,
