You are not permitted to download nor use the following updates unless you are a registered owner of MAX_FAX.

max_card Priority Update
01-03-14 max_card 4.2l
This version changes the default O/S priority value so that the idle priority (while waiting for an incoming call) is now 11 rather than 8, to prevent missing calls during heavy user activity. Added P=rx,tx,idle parameter to allow advanced system administrators the ability to tune the priorities.
The values are limited: 22 >= rx >= tx >= idle >=1
Download the executable max_card_42l

Y2K Update
While internally MAX_FAX uses time_t to store dates and times, the routine used to convert the date to readable form to timestamp log file entries was faulty. So for year 2000 dates, the date is incorrectly recorded as 100-MM-DD. The following archive contains fixed versions of the offending programs.

Download the update archive max_y2k.pax.F which contains max_admin, max_card, maxsend and maxsch only.

Download the full archive max42k.pax.F which contains the entire MAX_FAX package.

Install MAX_FAX archives as follows:
Login as root

MKLIB is a utility that allows creating a bunch of small .c source files and then have them automatically put into a library that can be used when you link. This does not create a shared library that lives in memory, but instead makes maintenance of many .o files easier for inclusion in your programs.

Read the details in the mklib.tgz.readme.

Dev.arnet is a Dev driver to support the entire line of Arnet asynchronous serial cards. There is a 32 bit version for QNX 4.23 and later and a 16 bit version for QNX 4.2x. It supports the following cards:

Extensive help is included which covers the various aspects of configuring the cards to avoid conflicts with other devices in your computer. Serial wiring diagrams for a wide range of applications are also provided.

Please note that Arnet products are now available through Digi International.

PlayCD is an audio CD player application written in Photon to work together with the Creative Labs SoundBlaster series of sound cards. It was written as a sample application, so you can follow the well-commented source code to see how things are done. The binary is also included, in case you do not have the Watcom C compiler available.

PowerHouse X10 is a system for sending signals through the power lines in your house to devices which can turn your lights and appliances on and off. A low-level interface provides a square wave, synchronized to the zero crossings of the mains 60Hz sine wave. It is necessary to provide a signal to this interface within 10 microseconds of each zero crossing in order to produce the packet used to signal the devices.

This is an excellent demonstration opportunity to show how a simple QNX and Photon application can be interfaced with a short interrupt service routine and showcase some of the graphical possibilities of Photon.

To provide a simple hardware interface, a standard serial port is used. Conveniently, the modem status lines will provide an interrupt on both a rising and falling edge, which is exactly what is required. The Dev.ser driver is not used, and the UART bits are twiddled directly by the interrupt service routine.

The Photon user interface allows the user to select the address of one device, command it to be turned on or off, and if on, command it to be dimmed or brightened. Since the packets take almost 1 second to transmit each, it is common for the user to get ahead of the device, so a current output status is also displayed.

So this example illustrates the following:
