MicroWIN 2000 Manual
Version 1.0
modem is initialized with the Modem Initialization Strings and the callout is made. To make
the callout, the Modem Dial String is used to prefix the telephone number so the modem will
know how to dial out to this number.
After the modem disconnects from the dialer, it is made available for any other scheduled
callouts. If need be, the Modem Hangup String is used to try and disconnect the modem from
the dialer.
Local: This port will be used to communicate to a dialer’s Printer Port using a standard serial
cable. A dialer hooked to a port will be connected to when a user tells the connection to occur.
COM Port Direction
InOut, In, Out, On Demand. This specifies how the port should be used.
InOut: Used for Modem Callouts and will accept dialer call-ins.
In: Only accepts dialer call-ins. No callouts will be made with this port.
Out: Only makes callouts. No dialer call-ins will be accepted.
On Demand: Only will callout when a user requested callout is to be made. No call-ins will be
accepted.
Modem Strings
These options are here because not all modems act the same or are programmed the same. If
problems occur with a modem, entering the appropriate modem strings should fix these. The
following also show the defaults which will work for most modems.
The Init Strings are sent to the modem before an actual callout is made. Each command expects an
OK from the modem before continuing on.
Init String 1: Default: AT&F&C1
Init String 2: Default: <Blank>
Init String 3: Default: <Blank>
The Dial String is sent to the modem appended with the phone number that is getting called. The
default is ATDT.
The Answer String is sent to the modem when MicroWIN 2000 senses that the phone is ringing. It
causes the modem to answer the phone. The default is ATA.
The Hangup String is sent to the modem when a normal drop in DTR doesn’t hang the modem and
dialer up. Initially, the string ‘+++’ is sent and then the Hangup String. The default is ATH.
