   The 'mildew' you are referring to is more likely to be 'CRT Cataracts' - a   
   condition where the safety glass (screen) that is bonded/laminated to the CRT   
   begins to degrade resulting in white spots that are often mistaken for   
   mildew.  A fairly common    
   problem that affects CRTs mfg in the 60s through 80's.   
      
   One way to clean up the face of the CRT is to remove the safety glass.  There   
   are various methods suggested that include using a thin wire placed between   
   the CRT face and the safety glass, and using a sawing motion move over the   
   entire CRT face,    
   effectively cutting off the safety glass.  Variations of this approach include   
   heating the safety glass with a heat gun, heating the wire, etc.  Google CRT   
   cataracts and you will probably find lots of ways to remove the glass.  Some   
   are better than    
   others.  It is often difficult to remove the remaining glue on the CRT face.   
      
   Not clear what you are attempting to do with the RPi and serial line. Do you   
   want to replace the MSDOS PC with a RPi and have it talk on a TCP/IP network?    
   If you just want to move bits around, you may want to look at SLIP (serial   
   line interface protocol)   
   .
