Hello all,

Trying to muck around with serial ports under Linux using ruby-termios.

There is some test scripts that came with ruby-termios,  
modem\_check0.rb is one example.

When I use the above script (modem connected and DEVICE pointing to  
the appropriate device file of course), I get the  
following error:

modem\_check0.rb:51:in `setattr': integer 2147483824 too big to convert to`int’ (RangeError)  
from modem\_check0.rb:51

Running Ubuntu Dapper Drake AMD64  
ruby 1.8.4 (2005-12-24) [x86\_64-linux]  
termios-ruby 0.9.4’
