Help? Problems with serial port

[rir@mediaone.net]

On a SMP slink system with a 2.2.10 kernel I am logging the following
from mgetty. The "Interrupted system call" makes me think this is
not just a chat script problem.

I am not sure what I should be looking at to fix the
problem.  

If mgetty is not run minicom works fine to dial out.
