Hi,   
      
   I do have a similar problem with tcpser and the Raspberry PI.   
      
   Excuse - it is about a connection between the PI and an Apple II :-) ... hope   
   that's also ok here.   
      
   The problem is that tcpser works, but after about 10-20 hours it shuts down.   
   The Terminal Window is still open and I can start it again. Then it is working   
   all right but the same shutdown again after the same time?   
      
   My setup:   
      
   Raspberry PI 2 Model B   
   Debian   
   Raspberry WiFi Stick   
   USB to serial adapter (USB0)   
   tcpser   
   Apple II connected to serial adapter   
      
   I installed tcpser with:   
      
   sudo apt-get install tcpser   
      
   Started tcpser with:   
      
   tcpser -s 2400 -d /dev/ttyUSB0 -p 6502 -ts -B /scripts/busy.txt -N   
   /scripts/offline.txt   
      
   As said, tcpser is running well, I can telnet to my Apple II - everything   
   works fine. But after a few hours the connection in the Terminal Window is   
   shut down. I start it again - working fine - after a few hours the same?   
      
   Thanks for any help!
