Re: [hylafax-users] MultiTech 5634ZBA v92 usb hungup during receiving.

["Joseph Teichman" <joe@xxxxxxxxxxxxxxxxxx>]

Okay, this is an update to the problem with the MultiTech 5634ZBA - USB - v92
occasionally locking up in the middle of a fax receive. They sent me a test
firmware, but I ran into the same problem. So, I just wanted to let you know
that so far, the problem has not yet been resolved. I am awaiting a response
from MultiTech and will keep you posted.
Joe
