This is a tiny program to check how long it will take to send/upload a file
through a Modem. The resulted transmitting duration is only a rough figure
because of different protocols, and the calculation is based on a best trans- 
mitting condition.

The DOS Line Command is very  simple and straight-forward.

duration <filename.ext> <BPS> </0>
  |          |             |     |_______switch to turn on/off answer mode
  |          |             |__________BPS figure, can be any integer number
  |          |___name of file to be checked, can be with or without directory
  |________the executive file itself.          

If issue a Command like: 
             
             duration myfile.zip 28800

then the program will display the size of the file in bytes, and the transmitting 
duration according to the bps the user has put ( here is 28800 bps).There is 
no limitation of how high the BPS can go, it can be any integer number.  And  
the program will also prompt a Yes/No question for the user to answer before it 
can terminate.

If issue a Command like:
             
             duration myfile.zip 115200 /0   

then the program will perform the same like under the former command, except 
it will not prompt a Yes/No question for the user to answer, instead, after
displaying the file size and transmitting duration, the program will terminate
by itself.

If anything is wrong, the program returns errorlevel 1, else errorlevel 0. 
If answer Yes, the program returns errorlevel 2, if No, errorlevel 3. 
If having switched off answer mode, the program returns errorlevel 4.

Four files are included in the DURA11.ZIP file:
DURATION.EXE
DURABAT.BAT (an example batch file)
ANYWAY.BAT (another example batch file)
DURATION.TXT (this file)
