Simple RS-232 Control

[lightswitch2159]

Hey guys,

Quick question. I need a simple way to send a string(%BE%EF%03%06%00%BA%D2%01%00%00%60%01%00\r) to a projector. Is there any way to do this with a .bat file so I can just click it and it turns on?

Thanks!

In the old days you could do that with a terminal program. Do they still have terminal programs?

Windows still has Hyperterm.

Alternatively, you could download Borland's TurboC (now a free download) and write a small C program to send a character string specified on the command line to the serial port (also defined on the command line). You can compile your C program using TurboC to create an executable (.exe) file and place that plus the desired string(s) into a batch file.

Vista and 7 don't come with hyperterminal anymore (something I run into with my job all the time). You can still use it, but it's something you have to find elsewhere. I'm wondering if you can open a hyperterminal file (with all the settings like baud rate, com port, etc) and then pass it that command. Let me know if anyone figures this out.

Sounds like a plan to me just I dont know ANYTHING about programing

If you still have this need I would be happy to whip up a little application for you.

Ok, the app is ready for you to test.
It is a small (<40KB) windows application that allows you to configure a com port as well as the command(s) you would like to send. You can save each individual command configuration in a file. If you turn on the AutoSend feature then when you run the exe and pass the file as a parameter it will send the command and exit the app. This should allow you to configure any commands you like and create batch files to execute them.

From a DOS prompt:

ECHO %BE%EF%03%06%00%BA%D2%01%00%00%60%01%00\r > comX:

Where comX: is com1: or com2: or com3: or com4:

This may not work on "advanced" operating systems such as Vista or Win 7 but it sure will work on XP and earlier.

And yes you may put this in a batch file and it will work there too.

How do you set baud rate, data bits, etc with the Dos method? That seems great to me except for those settings.

[FlamHappy]

Mode comx: 9600,n,8,1

But in windows you set that stuff up in control panel.
The default is 9600 n 8 1 and most devices made in this century accept that speed and protocol.

That rocks. I can think of tons of stuff I want to control serially that a simple batch file will let me do with a simple double-click.
