ComDrv 1.7
----------

Changes from 1.6 to 1.7:

    - several bugs which used to deadlock the driver are fixed.
    - IRQs were restricted to IRQ3 and IRQ4. Now IRQ0...IRQ7 work.
    - new option -B to set the baud rate.
    - new option -D to display diagnostics.
    - new option -R to transparently reset the driver.
    - new option -W to enable non-blocking writes.

The options -B, -D and -R can only be used _after_ installing the driver.
Example: To install the driver on COM2 at 19200 bps, one would have to
enter the following commands

  comdrv -c2
  comdrv -c2 -b19200

The option -W can only be used when installing the driver. When in non-
blocking mode, the driver will discard send requests when the output buffer
is full.

ComDrv is in the public domain and can be freely distributed and modified.
