This is a modified version of IBM's OS/2 driver (Jan-06-99) for USB modems.


Summary of modifications
------------------------

* fixed bug that caused system trap when connecting hardware other than 3Com.
* disabled detection of optional "COMM_FEATURE". My test hardware 
  pretends to support this command set, but it doesn't respond to them.
* fixed bug in send buffer handling (underflow during flush)
* enlarged receive buffer from 5K to 32K, because many communication programs
  do not handle very well buffer overflow conditions.


Known problems
--------------

* no VDD support for MSDOS/WinOS2
