                 POWEREXEC PROBLEMS WITH AT&T PCMCIA MODEM


PROBLEM:       The AT&T PCMCIA modem supplied with the PowerExec will not
               connect with some FAX devices.  As a result some software
               packages such as BitFax and WinFax will not communicate
               properly.

CAUSE:         The modem fails to hold the line causing the connection to
               falter and error out.

SYSTEMS
AFFECTED:      All PowerExec's configured with the AT&T PCMCIA modem.

SOLUTION:      Revision 1.45 of the flash firmware update for the AT&T modem
               corrects this problem.  Until supplied by AST the update can
               be obtained by dialing into AT&T's BBS.  The phone number is
               813 532-5254 and the file name is KIT145.EXE.  The firmware
               update is supplied with a readme file that details the upgrade
               procedures
