  Yay!  I'm glad other people are using this; it's awesome and updated often.  
  If you have problems with z-modem downloads, the authors added a switch (I  
  think --no-filter) to stop the null characters from being ignored.  You can  
  also convert to utf-8 from cp437 with a switch.  I have 2 ssh ports, one for  
  cp437 and one for utf-8 because of that.
