process hung problem + self reset

[aratti]

Very likely the problem is the time taken to dtmfout between the two serin command. If the for/next loop takes just longer than allowed you miss tx bytes and your system is out of syncronism. (Remember you have a wait comand)

Remove

dtmfout porta.3 ,100 ,100,[ 10 , 0 , 10 ]
             
             
     for x = 0 to 20
                   pause 10
                 if  gdata[x] = "." then
                    gdata[x] = 12
                    endif
                      dtmfout porta.3 ,100,100,[ gdata[x]  ]  
                       
  next x

And dtmfout after the second serin command, to be sure to avoid loosing tx bytes
