i was under the impression they all had custom drivers to suit the purpose.
UDP protocol is one layer below TCP/IP.
Ethernet needs no drivers, but protocols.
Re: Mach3, Mach 4 or Linux CNC for G0704
I can't answer for the others, but I can answer for the Ethernet Smooth Stepper (as I use one). It uses the stock standard Microsoft Ethernet driver.
However, there is a Smooth Stepper plug-in which takes high-level commands from Mach3 and converts them into ethernet packets. There is also a separate plug-in to convert those same high-level commands from Mach3 into a USB data stream.

Buffers - oh yes, buffers for sure. Won't argue there! You get to specify the size of the buffer you want to use with Mach3 and ESS.

Ethernet Powerlink uses standard Ethernet hardware (unlike Ethercat that uses standard hardware on the master but proprietary hardware on the slaves)
but it does use a special driver
Our Ethernet hardware uses standard drivers, protocols, and hardware but like Ethernet Powerlink, requires a RTOS
In either case, standard Ethernet traffic is not allowed on the real time link as it will normally increase jitter to an unacceptable level by
blocking real time traffic

Last I looked, TCP and UDP were both Layer 4 protocols.

Re: Mach3, Mach 4 or Linux CNC for G0704
TCP/IP is basicly UDP protocol + error handling and handshake.

Yup, but they aren't on different layers of the OSI model. They're both Layer 4.
