SupraFax 14400 modem?
10 messages in this thread
My husband is getting a SupraFax 14400 modem for his PC for Christmas. I'd
like to use it with my Amiga too! What software comes with the modem, and
do I need to order the Amiga version? (I'm not particularly interested in
the FAX option right now).

What you may want to do is purchase the amiga version with software so
that if you do want it later you will have it, and then purchase the IBM
software separately. IBM compatibles have a wide selection of both
communication software and FAX software available, so you will be able to
select the one that fits your husbands needs best.

A client just got the SupraFax 14400 modem for his Amiga.
The IBM software was an extra $45 – if ordered direct from Supra.
(The same may be true for the Amiga software).
Enjoy,

Jane: I use the SupraFaxModem with my Amiga. The modem hardware is
identical to the IBM version, with one possible exception: The Amiga
bundle comes with a specially configured serial cable that enabled the CTS
firmware handshaking. This resulted in more reliable links than, for
instance, the usual XON/XOFF software handshaking. You can use a plain
serial cable but you lose efficiency. The IBM version should come with the
special cable. If you're planning to move the modem between computers by
moving the original cable, no problem; if instead you're planning to use
an A/B switch box, you may need to go out and spend $10-20 for another
specially configured cable.
Just about any Amiga terminal software will work with the fax modem, but
you may have to tweak the configuration. Remember that to max out the
modem, you need a package that can run at 57,600 bps — that's the fastest
effective rate at which the Amiga will exchange compressed data with the
modem, whatever your on-line speed. Examples of commercial term software
that'll handle that rate are Online Platinum and AtalkIII. Shareware stuff
like Term 2.4, Ncomm and JrComm also should work, though maybe not at the
fastest rate.
If you use the modem for faxing, you'll need GPFax, a wonderful program.
It is sold unbundled if you want to add it at a future date. About 75
bucks. The bundled Amiga version of the Supra modem also came with ATalk
III, which has worked flawlessly for me. You can buy it unbundled for
about 40 bucks.
By the way, depending on the hardware setups of your Amiga and your
hubby's PC, you may be able to claim bragging rights. Some PCs have
trouble keeping up with the Supra's fastest speed because they have a
bottleneck chip called a UART. The Amiga doesn't have a UART. If you have
an unaccelerated A1000, A500 or A2000, your 68000 processor may likewise
be too slow to keep up. It's helpful in that case not to multitask, and to
boost your serial port buffer in Prefs (I use 512K). With my Amiga's 68030
<continued>
processor, I have downloaded at rates of up to 2500 characters per second!
No PC I'm aware of can keep up with that, even with the latest UART chip.
P.S. For more info on the modem, you and your hubby should check in on the
Supra conference elsewhere on C.I.S. Lots of talk about the 14400 modem.
Ron,
I have the Supra 14.4k modem…could you tell me *exactly* what
drivers/packages you were using when you got 2500 CPS? What setting were
used in prefs, what XPR library, what telecom package…everything! How
many colors are in your workbench screen…
My 28mhz '030 machine has not been able to do anything like that, in terms
of performance. Of course, it could be the BBS's that I connect to,
also.

It's probably the particular BBS, more than anything. I more typically am
getting aroudn 1,600 cps. I use several packages but that day was running
ATalk III. I set the computer-to-modem rate at 57,600 baud in the
software. I had the serial prefs buffer at 4,096, connect rate at the top
(31,250) and handshaking on RTS/CTS (hardware). Standard Zmodem within
Atalk, not an XPR library (haven't had much luck with 'em). I used the
modem init and dialing prefixes that ATalk was set up with (it came
bundled with the Supra). I was running an 8-color Workbench in overscanned
interlace.
Ron,
Thanks for the info.

He must be downloading/uploading files that are not compressed with
something like LHArc or ZIP. Higher speeds are easy with uncompressed
files and a v.32bis connection. I max out at around 1650cps with well
compressed files when connected to either a USR Dual Standard or another
Supra 14.4k modem. This is with an A3000 and JRComm.
