Please edit the Cenmodj.dat file to suit your system set up.
It is as follows:

2           ' Comport you are using
2400        'Speed to 56,400
C:\RECV\    'Download Directory With The backslash
C:\SEND\    'Uload Directory With The Backslash
TRUE        'Weather Your Local System Can Do Color If Not FALSE

Be sure there are no blank lines, no spaces, and use askii word
processor like QEDIT.   This worked fine on my system.  I reconfigure
the comm prot.  then set it back to normal.  Set default buffers at 128
and this precludes the Disk buffer.  Hope it worksd for you...
Please read the docs for further information.  Enjoy..
