5.15 What fax modems will work with the NeXT?

fax modem, on NeXT

Most available modems of today, don't work for with the general fax driver available with NEXTSTEP. In this case you need to perchuse a commercial solution: 'NXFax'. There are demos available. The following information is pretty much old, and might probably be obsolete now:

The following fax modems are currently available for the NeXT Computer:

Manufacturer, Model Supplier, Type DoveFax for NeXT, Dove Computer, Class 1 HSD FaxMaster, HSD Microcomputer, Class 2* mix fax, i�link GmbH, Class 2** SupraFAXModem V.32bis, Supra Corp., Class 2 (requires DFax driver or NXFax driver) ZyXEL U-1496E/E+/S/S+, ZyXEL USA, Class 2 (requires NXFax driver) Telebit T3000 with fax option Telebit WorldBlazer with fax option (requires NXFax driver) Neuron 1414/1414+ with ZyXEL ROM upgrade (requires NXFax driver)

(Neuron 1414 and Neuron 1414+ modems are relabelled ZyXEL modems. Contact ZyXEL USA for ROM upgrades. Neuron modems with 512K ROMs should upgrade their ROMs and ROM sockets to 1 Mb ROMs. People with 1Mb ROMs should just order the new ROMs.)

(*) Note that the Class 2 is not yet approved; it is still out for ballot, after having failed in an October 1990 round. The Abaton InterFax 24/96 NX driver supports Class 2 as it was in that draft; there are expected to be very few changes prior to approval.

(**) Note that mix fax works with both the October 1990 and October 1991 draft versions of Class 2, especially with the NeXT supplied Class 2 modem driver. Upgrading to an approved version of Class 2 would be a matter of just a software update (holds true for any forthcoming (class 3?) standard, for that matter).

In order to use a fax modem with the NeXT Computer, a NeXT compatible fax driver must be available to operate the modem. Modem control procedures may be proprietary or conform to one of the following EIA/TIA standards:

Class 1: CCITT T.30 session management and CCITT T.4 image data handling are controlled by the driver.

Class 2*: CCITT T.30 session management and image data transport are handled by the modem. CCITT T.4 image data preparation and interpretation are controlled by the driver.

Release 2.0 of the NeXT system software includes a Class 2 modem driver which will work with any fax modem which meets the EIA/TIA Asynchronous Facsimile Control standard. Other fax modems must supply a NeXT compatible driver.

Note that there's a small bug in 2.0 (fixed in 2.1): a symbolic link is missing for the file Class2_Fax_Modem_Driver in /usr/lib/NextPrinter. The simple fix: create the link; it should reference Interfax_Fax_Modem_Driver, also in the /usr/lib/NextPrinter directory.

An alternative workaround for Class 2, especially useful for novices: just use InterFax as the modem type in PrintManager, rather than Class 2*.

After installing a fax modem using PrintManager one must repeat setting things in the Fax Options panel in order for them to be stored correctly. In particular, these include the Rings to Answer and Number of Times to Retry. This affects all fax modems being installed.

If one uses illegal characters in the Modems Number field in the Fax Options when configuring an InterFax modem then the modem will not answer the phone. Legal characters are digits, spaces, and plus signs. This does not affect the Dove modem.

Modems from the german vendor Dr. Neuhaus also work with the internal Fax-Driver. But only the FURY-series does.
