THE AOPEN FM56-ITU FAX/MODEM
me a MODEM which is economical, works well and is one I can control. By
control I mean a MODEM with jumpers and a wide selection of IRQ and port
address options. The Aopen FM56-ITU meets these requirements.
The FM56-ITU is a non-plug and play, ISA bus
FAX/MODEM with old-fashioned jumpers to set the IRQ and COM port address. One
does not have to have a PCI MODEM to have a fast MODEM. The ISA bus
runs at 12 Mhz. It is far faster than any demand that a
56K MODEM can impose. Also, an ISA MODEM can be used in a wider
variety of computers. Furthermore, I prefer jumpers, especially when
installing a MODEM in a computer with a motherboard with misbehaved COM ports
(ports disabled in the CMOS Setup, but still detected by Windows 95/98) and
machines in which there are so many expansion boards that Interrupts have
V.90/K56Flex standard. I have tested this MODEM with Internet
Service Providers (ISPs) running V.90, K56Flex, and X2. It works flawless
with all of them. Of course, it can only run at 33.6 KBS when talking
to an X2 MODEM. In my locations it runs 42 to 46K when connecting to
V.90 or K56Flex MODEMs. These are typical speeds for 56K MODEMs, which
can connect at a max speed of 53K in the U.S.A. in very ideal conditions--the
FCC limits the maximum speed of voice telephone lines to 53K.
has the Rockwell RCVDL56ACFW/SP chipset and a 16550/A
Compatible Enhanced UART.
MODEM is easily jumpered for COM1: through COM4: and IRQs 3, 4, 5, 7, 9,
10, 11, 12, and 15. All of he jumpers are on a single header. All
of the combinations of COM ports and IRQs are silk-screened on the board
and easily understood. (I would be happier if the jumper header were
located near the top of the board where it could be jumpered without removing
the board from the computer.)
speaker is no wimp. It can be clearly heard outside of a closed computer
are connectors (and cables) to connect the MODEM to an Acer motherboard for
wake-up on ring and to pipe the speaker sound to a sound card. The
sound cable plugs right into the AOpen FX-3D sound card. I have
made it work, with some finagling, with other sound boards as well.
Windows 95/98 the MODEM shows the actual connect speed (some show 115,200
BPS regardless of the true speed).
works well with DOS applications.
answering machine (TAM), voice mail, caller
ID and distinctive ring detection functions are supported.
has two RJ-11 and two audio jacks (speaker and mike).
Micro Software's QuickLink MessageCenter III software is included.
of course, you can use it as a 14.4 send/receive FAX.
Overall, a very good product, and the price is
