	Below are Notes regarding the DIGI_OS2.sys V 1.37.3 Beta driver


	Enhancements


	Bug Fixes

        digi_os2.sys
        ------------
          1. Fixed a problem where outstanding reads were not being
             flushed on the last close.
          2. Added support for setting output DSR (ODSR) and DCD flow control 
	     (e.g: mode com3: 9600,ODSR=ON).  Note that input DSR (IDSR) flow
             control is still not supported, and attempts to set it will be
             ignored.
             

        Known Limitations

          1. The current name convention supports "COM*" or "DIGI*" device
             names only.  There is no current support for user supplied
             port names.

          2. Altpin (as in the XALL.SYS driver) is not supported.

          3. Set modem line signals are overridden by hardware flow-control;
             i.e: RTS and DTR are not changeable when flow control is set on
             (see dmode.exe for setting RTS and DTR handshaking.)

          4. Instantanous error reporting is not supported.

          5. Input DSR flow control (IDSR) is not supported and setting it
             will be ignored.

	Below are Notes regarding the DIGI_OS2.sys V 1.37.2 driver


	Enhancements


	Bug Fixes

        digi_os2.sys
        ------------
	1.  Fixed a problem where, in shared interrupt environments,
            interrupts generated by the digi_os2 driver could confuse other
            cards.
        2.  Fixed a problem that caused the driver to crash on loading if
            more than 99 ports were allocated (e.g: /T:xx:43).

        digidevf.exe
        ------------
        1.  Added support for PCI Xr-920 (2, 4 and 8 port)
        2.  Fixed a problem where digidevf failed to recognize Digi adapters
            in slots associated with PCI Bus values greater than 0.
        3.  Changed version to 1.4.




        Known Limitations

          1. The current name convention supports "COM*" or "DIGI*" device
             names only.  There is no current support for user supplied
             port names.

          2. Altpin (as in the XALL.SYS driver) is not supported.

             i.e: RTS and DTR are not changeable when flow control is set on
             (see dmode.exe for setting RTS and DTR handshaking.)

          4. Instantanous error reporting is not supported.
