Help Using Modem & CLI

I'd like to be able to access my modem with the standard hayes command set from the CLI. In IBM DOS the command would go: ECHO ATDT5550000 >COM1: This would dial the phone # 555-0000 by using the modem on COM1. The reason I would like it might prove worth while to others. I plan to get a simple burglar alarm with a motion detector and a lamp module that automatically comes on when the motion detector senses something. Rather than a lamp I plan to plug my Amiga power supply into it. Then while I am away from home on vacation I can have the computer automatically start if the house is broken into. My Amiga will boot up and run the CLI dialing command which will call me where I am vacationing. However, to get this all to work I need to be able to access the serial port via CLI. I tried a similar command as in the IBM example (substituting SER: for COM1: but it didn't work).

Why have it dial you were you Vaction at. I would think you would want it to call the police dept. first. –Paul–

Paul, Many localities do not allow automatic dialers, tripped by alarms, to call safety services.

I wander why? I guess it would be all the false alarms.

Yeah, the false alarms tend to be more than police dispatchers can handle… most alarms are triggered by accident (ie: a resident or family member opening a door and forgetting to turn off the alarm or forgetting a reset code, a worker entering the residence unaware of an alarm system, etc.). That's why most systems are monitored by private companies who try to confirm what tripped the alarm BEFORE calling the authorities.

I doubt the police would know what to do with a piercing modem tone. I figured I'd call the neighbors (a friend) and they could check it out and/or call the cops.

Frank: You wouldn't necessarily need to run the serial commands through the CLI. You could instead boot into a terminal program that supports running an Arexx script at startup. The computer would boot into the term program, run the Arexx script, and give you a call. // \X/ John – (TechnoJunkie at heart)

I've come to somewhat the same conclusion about getting a terminal program to automatically run. However, I know absolutely nothing about Arexx. However, there is a neat little program that resides on compuserve called scripit. This programs records your input into ANY program, all mouse moves, clicks and inputs. Then you run the script and it does exactly what was recorded (even takes the same length of time you took). I then call this program from the user startup-sequence. So now the computer will sit there, the motion detector will detect any movement, start the computer, dial my number and I will hear the modem tone as I pick up the phone. The computer will disconnect due to the lack of modem connection and I'll call my neighbors. A pretty inexpensive way to monitor your home.

Great Frank, glad you found a solution for monitoring your home. Sometimes if a direct solution is not easily found, then it's better to improvise. So it looks like your Terminal program and scripit will do the job nicely. Have a nice vacation and hopefully your monitor will never have to be used. // \X/ John – (TechnoJunkie at heart)

>>A pretty inexpensive way to monitor your home.<< Yeah, and pretty haphazard as well. It works only IF: a) the power is on in your home b) your neighbors are home (most break-ins occur during the DAY, not at night) c) you are at the phone # you told the computer to call (doesn't sound like the kind of vacation I'd want to take!) d) somebody responds to your request for help within 5 minutes of the break-in… crime stats say that burglars rarely are in a home for more than 3 – 5 minutes. And, of course, if there is a thunderstorm while you're on vacation and the power in your home just flickers, the computer will reboot and call you with a flase alarm… only you won't know it's false. Just some food for thought.
