How to verify UDP vs TCP

We have recently had to replace an old Turbo PMAC that had separate cards for the CPU and Ethernet (connected together in the same module) with one that has the Ethernet interface integrated on the CPU board. We used the setup utilities to choose UDP communications (which appears to be the only protocol supported on the old cards). However, because of problems we had with communications I was never convinced that the card was set up properly with UDP rather than TCP.

 

Does anyone know of a way (I-value, etc) that you can check the protocol without using the Delta Tau utility?

This can only be done with the USBEthConfig program.

 

Presumably that program uses some communication with the card that could be accessed in another way?

 

To the best of my knowledge the older USB/Ethernet boards supported TCP.

 

From the Accessory 54E Manual, January 27, 2003: "The PMAC embeddeded ethernet communications card talks using the UDP protocol of the TCP/IP suite of protocols on port 1025. Therefore the programmer should open a datagram socket on the port 1025 the PMACPORT." But maybe that is incorrect ...
