     RT-> ver.516 seems to be alright.

V.502 works at V.34, not at K56Flex.

The ROM mask of v.502 was cast before Lucent even got into the mix. That is 
the code that Rockwell supplied to vendors using both fixed and Flash ROM 
architechtures. That was all they had to offer.

Ascend was the first to market with any K56???? server, and what they were 
using was K56Plus. That is the _only_ server code that Rockwell had to offer.

The Hayes swap program is in effect now.
