Connecting Online without Communications Software
This section describes how to connect online via modems without using communications software.
Registering RS-232C Interface Driver in CONFIG.SYS
Use a text editor or word processing software to add the following line to CONFIG.SYS.
DEVICE=A:\DOS\RSDRV.SYS
Specify in the underlined section the drive and directory in which the RSDRV.SYS file resides. In this example, the
file resides in directory DOS in drive A.
Creating and Executing a Batch File
Create a batch file for setting the computer communication conditions, modem, telephone number, and dial-up.
A sample batch file for the ME2814B III is shown below. These files can be created using a text editor. In this exam-
ple, the baud rate is 9,600 bps and the dialing method is tone dialing.
@ECHO OFF
MODE COM1:96,E,7,1
ECHO ATY0X3&H0&K0&M4&N6S0=1S15=128S19=10&D0&W0DT045-123-4567 > AUX
ECHO ON
The underlined section indicates the other partys telephone number.
For the meaning of each AT command, refer to Modem Settings earlier in this appendix.
Execute the batch file at the DOS prompt to connect the line, then operate the Controller Link Support Software as
usual.
Note Before starting the Controller Link Support Software, always make sure that the line is connected.
