[Serusers] ser_fifo permissions

[Cameron Beattie]

This seems such a basic question but I haven't found the answer anywhere. 
How do I set the permissions on the ser_fifo file without running chmod?

I tried setting user = and group = in ser.cfg but that didn't work. I don't 
want to have to chmod the file each time I start ser. I'm sure this is very 
simple and would appreciate any help.

Regards
