Emerging Technologies also makes sync cards with drivers supported under 
BSDI, FreeBSD and some forms of SysV UNIX. 

They have been discussed on either (or both) the inet-access and 
bsdi-users lists in the past. Archives for inet-access are at 
(or is that and for bsdi-users at There is 
sometimes a search engine available for bsdi-users from a link at

I got my info by emailing dennis at but you could phone
