rtnet and network card compatibility

[syga@freesurf.ch]

hello all,

i am trying to use rtnet to get hard real time monitoring. i have 
installed it with no error at all. however it seems to work only with 3 
kinds of network cards. is this right. i do have a 3C5098. will it work? 


what do i have to do otherwise?? change the card??

another question: how do you start rtnet?? if i do type "rtnet" at 
prompt, nothing happens!!

is there any man page about rtnet?? or any information how to use option 
or...

thanks in advance.

regards, sylvain
