[comp.periphs] Need to read bare synchronous RS-232

I need to get "raw bits" into a Sun workstation which are presented in
unencapsulated, unframed, un-CRCd synchronous RS-232 form at 20,000 or
40,000 bits/second.  The Zilog chips in the Sun CPU ports and SunLink
MCP boards won't do this - they want SDLC, monosync or bisync frames.
There's nothing in the Black Box catalog which will convert this bare
synchronous data to asynchronous either.  Can anyone suggest a VME board
that can get this data in?  (There is framing and CRC information in the
data stream, but it's in a form chosen by NASA and probably unique to
the satellite that originates the data.)
