Subject: ANchor Volks 6480 modem

Does anyone out there have a modem overlay for MEX, IMP or MODEM7
to allow use of a Anchor Automation Volksmodem 6480?  It's not
Hayes- or anything else-compatable.

I got it partially working with MEX using the C128 overlays as samples
and borrowing sections of code (timing, etc).  It "almost" works in
terminal mode but gets lots of data errors, primarily character swaps
not garbled characters.  It looks like the first character of a line
will show up later in the text.  I know its something I'm doing wrong,
but haven't figured out what yet.

By the way, this is the modem you get if you order the 300/1200 baud
modem for a C64/C128 for $79 from Protecto. Programming info is non-
existent with the modem, but Anchor will send you some cryptic 
photocopied sheets which consist mainly of a assembly language
listing of a dialer routine. It has almost no comments and uses
very descriptive labels such as "d", "g", etc.

If you are thinking of getting a 1200 baud modem for your C128, stick
to the 1670. I have seen them advertized in the mags for as low as $99.
The extra $20 is well spent

I have no association with Anchor or Protecto except as a not-very-satisfied
customer.
