flexfax: MPS Problem in ZyXEL U-1496E

[CN Liu <cn@mail.sinyih.com.tw>]

Hello!

I would like to share my experience solving MPS Problem in ZyXEL
U-1496E.

I used to have problem sending the whole fax pages from this modem. The
results of sending to 4 different fax machine are the same -- multiple
copies of the first page of the document were received and the rest of
the document was missing.

I had read the posting from "Harald Pollack" dated March 31,1998. I
learnt a lot from this posting but my problem look unlikely to be the
case he stated.

Fixing this problem is simple: replacing the modem (firmware=V6.13) with
another one (V6.16), and finish!

Enjoy

CN
