Using the Anchor Mk XII within BYE.COM
To use the Mk XII you must ascertain if you have the proper rom set.
This can be done by connecting up the modem and typing ATI1 the result
will be a number if the number is 218 then you are ok, if not get on the
phone to Anchor and get them to replace the roms in your modem. This fixes
a nasty habit of the Anchor's which will cause a seizure of the worst kind
if someone calls your modem at 300 baud. Apparently the modem gets confused
when it answers and has to switch baud rate hanging up the entire system.
Thanks to Ed Richter for this information. This tip and the following mod
allow the Anchor to function as a Hayes clone in a BBS situation.

DTR Hangup mod for Anchor MK XII by Barry A. Cole 30 JAN 1985
----------------------------------------------------------------
This will cause a full reset when DTR is brought high(-12v). This
follows the standard definition of RS232 and makes the Anchor
compatible with the Hayes Smartmodem for usage within "BYE.COM".
Installation:
1)Open the modem case using a wide blade screwdriver. Pry the top
separate from the bottom.
2)Solder the banded end of a small switching diode such as 1N914 or 1N4148
to the RS232 connector pin 20. Keep the lead long and insert in a piece
of sleeving stripped from a wire. Looking from where the ribbon cable
enters the board, this is the center of the 7 pins in the 2nd row from
the outside of the case.
3)Solder the other end of the diode to a piece of wire. Slide sleeving
over the exposed diode lead for insulation.
4)Solder the other end of the wire to the plus(+) side of capacitor C48.
This was in the farthest corner of mine. On newer boards, it is near
the center of the board.
-----> That's all- not bad for 10 cents! If you run a Kaypro, see my
program HANGUP.ASM to see how to use this. Most versions of BYE
try to drop carrier via DTR even if they think you don't have it!
