           *** M.I.B. ACCOUNTS USING HAYES 1200B INTERNAL MODEMS ***

SYMPTOM:  M.I.B. communications software fails after replacing the modem
during maintenance.

PROBLEM DETERMINATION:   When ordering PC415, you may receive either a
full length or half length internal modem. There is a slight timing
difference between the two modems that only effects the M.I.B. software.

FIX:  When ordering PC415 for an M.I.B. account, make a note on your order
not to substitute. Peggy Lafferty is aware of the problem. This will stay
in effect until M.I.B. comes up with a substitute modem or a fix for their
software.

           *** Hayes ACURA 14400 modem configuration onformation ***

Attach the modem to a terminal or a pc to submit AT commands.

Power the modem on.

Enter: ATQ1E0       Turn on echo and response codes.
Enter: AT&V         to display configuration

The top line will display:
ACTIVE PROFILE:          DTE:9600  DCE:      PARITY:EVEN

The above display CANNOT be changed by registers, it is determined by the
configuration of the port on the system (or terminal) that the modem is
connected to.  In other words, if you are going to connect this modem to a port
that will be configured for 9600 baud, even parity then you should connect to
the modem with a terminal of port set to 9600 baud, even parity.  The modem
handles data bits so we don't have to be concerned about that.

If ``cu'' is being used to connect to the modem use the following to connect
with even parity:

     cu -e -ltty2A       (Assuming that in the Devices has the following entry:
                          Direct tty2A - 9600 direct)

Check the following settings also:

@K3       RTS/CTS flow control  @K4     XON/XOFF flow control (Pick one)     
@D0       Ignore DTR
@Q0       Communicate in asynchronous mode
@A0       Connect as answering modem when auto-answering
S37=9     Maximum DCE (phone) line speed 9=9600

AT&W      To save profile
