  past 8 months and it works perfectly.
  All original documentation, components and packing material.

  this is quite an up-to-date modem featuring hayes AT command set, V.42bis
  and MNP-5 data compression and error correction plus all the other specs
  that I've extracted from the user's manual and listed below, I haven't
  had any problems hooking up to any other modems with it.

  price: $210 or best reasonable offer.

purchaser pays COD and shipping on any parcel carrier they wish to use.

there's more info but I'm sick of typing at 2:00am in the morning, both
modems pretty much have the same capabilities (barring speeds) and seem to
me to be your typical MNP 5 Class Hayes compatible modems.  If you need
more specific info I'll be glad to reply to questions individually.
