         Subject: Patching FAXtool to work with new SPARCbook 2 modem firmware

         The versions of faxsend, faxreceive,  and faxclient distributed
         with the Solaris 1.0.1 SPARCbook Version B.1 and B.1.1 operating
         system releases do not recognize modem firmware Version 1.000.
         If you are encountering the error "unidentified modem" when
         attempting to send a fax with FAXtool or faxsend, check the
         version of the modem firmware by doing the following:

          1.  Connect to the modem via cu

                % cu modem96

          2.  Display the version of the modem firmware

                ati3

          3.  Disconnect

                ~.

         If the modem responded with "V1.000",  follow the instructions
         below to patch faxsend, faxreceive, and faxclient.

          1.  Login as root and change to the /usr/bin directory,

                # cd /usr/bin

          2.  Create a backup copy of faxsend,  faxreceive, and faxclient,

                # cp faxsend faxsend.orig
                # cp faxreceive faxreceive.orig
                # cp faxclient faxclient.orig

          3.  Fix the ownership of the faxsend and faxreceive copies
              (faxclient is owned by root),

                # chown uucp.staff faxsend.orig faxreceive.orig

          4.  Use adb to change "V0.310P" to the new firmware version
              "V1.000"

                # echo "850b?W 56312e30; 850f?W 30300000" | adb -w faxsend
                # echo "8593?W 56312e30; 8597?W 30300000" | adb -w faxreceive
                # echo "aeeb?W 56312e30; aeef?W 30300000" | adb -w faxclient

         If you should experience any problems with this procedure, please
