   If it's short enough. Telix has a 17-character limit in the phone book so   
   longer hostnames or IP+port combinations won't fit.

   Well that's a shame. I wonder why that was omitted. It works in the Linux port   
   and Android is very closely related...   
   I have DosBox Turbo on some of my devices so I opened up the .conf by hand.   
   Sure enough the serial stanza is completely absent, and even if you add it in   
   manually the application doesn't react to it at all.
