Uhm, do you have the modem programmed to not output any status messages?
All you want the modem to do is assert CD, but not have any "RING" or
"CONNECT" messages spit out.  It's possible that your (uu)getty is seeing
those messages as an attempt to log in.  Make sure you're modem is set to
"quiet" mode.  On my T1000 in enhanced command mode, I have it set to

    ATE0 Q4 S51=255 S52=1 S53=2 S54=3

(I put in spaces to make it more readable).  I have that saved in the NVRAM.
Check your manual, there's a section on suggested unattended S-register
settings.  I used that as a starting basis.

This seems to work fine under ESIX SVR3.2.2-D.  Perhaps they'll work for
you.
