Re: [hylafax-users] MultiTech ISI5634UPCI/8

There is no equivalent downgrade from 1.32i to 1.25p for the ISI5634UPCI/8.  I am also surprised that that downgrade fixed the problem below. The only reason I had seen people
downgrading was because of lockups not connect issues. Also (this question is for Mike) I thought the lockups related to 1.32i had to do with your phone lines getting wet or some such thing (see email as of 4/18/2005). Is that not so?

I don't know if this is related. However I recently pretty much eliminated
the above error by downgrading the firmware on another brand of
multitech modem (MT5634ZPX-PCI-V92) from 1.32i to 1.25p.

I would assume there is some common code between the different firmware
and it might be the cause of your problem.

Steve Tuckner at Multitech provided me with 1.25p firmware awhile back.
He might be able to shed some light on the potential problem you have and
the one I had.
