[FADCA] Hep w/ PK232

Thu, 26 Feb 2004 12:17:35 -0500

I have 7 pk232s -- kinda of a fan.

Have the schematics/manuals  as well as the service manual

But, a schematic is all you need.  One thing I would try is to open it up,
and take out the battery (or remove the shoring plug that connects the
memory backup battery)   one of the know 'problems' with the 232 is that
once it gets into HOST mode, you can't get it out.   Dropping the battery
backup to the ram to let it reset,   fire it up .. and hit *  (astrick)
several times  AS THE FIRST CHAACTER EVER SENT TO THE PK232 -- and it will
autobaud to your terminal rate.

If that don't'work -- I can email you a scan of the schematic-- it is a
simple circuit -- z80,  2 roms,  ram, and some modem stuff, etc.

Cheers

Rick
