Bridging ARCNET and Ethernet
Is there a way to transparently bridge ARCNET and Ethernet?

No. The topologies are too different to provide transparent bridging.

Driver for QNX 6
Do you have drivers for your Ethernet cards for use with the QNX 6 Operating System?

We do not currently have a driver for QNX6. We are planning on supplying one in the future. For the moment you can use the devn-ne2000.so driver but you may have some minor glitches. When we release our driver, it will correct these glitches.

The "ctne2000cfg" Program
What is the program “ctne2000cfg” and what is it used for?

This program has a dual purpose. It is intended to configure the card for regular use (I/O address, interrupt level, etc.) and also to configure the boot parameters used by our Boot ROM chips. Note that the card is configured with the boot parameters, not the Boot ROM itself. Since this is the case, the card’s boot parameters can be configured without the Boot ROM installed. However, they will have no effect on the operation of the card until a Boot ROM chip is installed.

For those who want more technical details: The card has a small non-volatile memory chip (EEPROM). This EEPROM holds configuration information. The ctne2000cfg program modifies the EEPROM contents to set the desired card parameters and to add Boot ROM parameters. The card’s controller chip reads the contents of the EEPROM to determine the card parameters whenever the card is reset. The Boot ROM reads the EEPROM at boot time to pick up the boot parameters.

Full Duplex Operation
What is full duplex operation?

Running an Ethernet card in "full duplex" mode means that it can transmit and receive data packets at the same time, effectively doubling the theoretical maximum throughput rate. Full duplex operation is not possible when using a hub -- only Ethernet switches support full duplex operation
