Re: [hylafax-users] modem wedged - MT5634ZBA-V92 serial

[Angelo Scagnetti <as@xxxxxxxxxxxxxxxxxxx>]

 Probably you're right, I've seen a recent message
on the list confirming your theory. I'm using an HP
ML 110 G5 as server and as stated in the message,
the serial port of this machine may be used as
console port only. And when I reboot the server
to fix the problem, I don't have to power-cycle the
modem to get it up and running again. So the
problem could be really there, on the serial port.
I'll try to fix the problem using an USB to serial
convert. Do you think it could be the right solution?

Many thanks, for your help.

Cheers,
  Angelo
