commit bb20d0b5b898ddc3506742ca7e9309ebe724b4fd

    SBS-1 ASCII output changes suggested by JungleJet
    
    1) Populate Field 3 witn "111"
    2) Populate field 4 with "11111"
    3  Populate Field 6 with "111111"
    4) End the record with <CRLF>, rather than just <LF>
    5) Increase the ctrCommon buffer size to cope with additional field data
    
    Apparently, this makes the output more compatible with Plane Plotter and
    RTL1090.
