   Create the device /dev/ttydm0 with major number 32 and minor number 128
   and use that instead. The serial line drivers are all written to use modem
   control by default on lines with minor number > 128. This is how I am set up
   here ( I use a Telebit T2500 ) and uugetty and cu co-exist happily.

   Note that I do have a problem with kermit; 
   kermit creates its lock file in /usr/spool/uucp rather than /usr/spool/locks, 
   which is where cu and uugetty create their lock files. The other problem, 
   as you pointed out, is that kermit needs to run as uucp to be able to access 
   the line as uugetty and cu make uucp the owner.
   I have submitted a (Mips) bug report for kermit .

Could part of the problem be that Jerry is using tip, and you are
using cu?  Maybe tip has the same problem that kermit has? 

Make sure that you have the kernel option (man kopt for info)
_riscos_ttys_default_clocal set to the default to get the scheme
mentioned above to work.
