Send Commands RS232?
Jul 26, 2010I have downloaded the vb script and it works as it should, its a program where you have some buttons so that you could trigger the relays.But i need several small scripts, one for each relay on / off so that i can call them from a .bat file with argument.i have a .bat named relaycard and in thet i have created argument like
relay1on
relay1off
relay2on
relay2off
and so on.
The small program relay1on should just do the jobb and then close itself.Maybe its a little bit clearer now.On the link that i posted there is a manual and even links to the vb program,

View 1 RepliesCall A Remote Modem Using A Local Modem Connected Via USB?
Oct 12, 2011I am attempting to call a remote modem using a local modem connected via USB. Programming language is VB.NET and I am using the SerialPort control to talk to the modem.
Communication is as follows:
I send: ATZ0[CR]
Modem responds: ATZ0[CR][CR][LF]OK[CR][LF]
I then try to dial a number:
I send: ATDTnnnnnnnnnn[CR] where nnnnnnnnnn is a valid number
The modem responds with:ATDTnnnnnnnnnn[CR][CR][LF]ERROR[CR][LF]
All other commands seem to work without any issues
For info the modem is a MultiTech MT5634ZBA-USB-V92
If I use hyperterminal and type the same commands in it works as expected and dials the number, so it must be something I am doing in my code, possible some setup in the SerialPort control
Communications :: Send A Command Via RS232 Communications
Jan 26, 2009I am using VB2008 Express and am curious how to send a command via RS232 communications. The string that I need to send is 02h PON 03h. The start and end bits are 02h and 03h.
How can I convert 02h and 03h to its ascii form. In hyperterminal, I use the sequence {(hold)ALT 0 0 2} on the number pad to send the start bit.
I am using this code currently without the start and end bits

Read Data From Rs232?
Dec 4, 2009My program connects via the rs232 port to a pump and it managed to start the communication and sending data. But the problem arises when i try to read the return signal from the pump to pc. This is the piece of code i've used:
Code: Dim returnbyte(0) As Byte Dim ByteIndex As Integer = 0
Do While ClassSerialPort.BytesToRead <> 0 ReDim Preserve returnbyte(ByteIndex) returnbyte(ByteIndex) = ClassSerialPort.ReadByte() ByteIndex = ByteIndex + 1 Loop
[code]....
I obtain the following results:
Code:... 6 12 0 0 0 92 ...
From the manual i understand which byte to read. For e.g 6 = ACK. The problem is how to interpret the 4 bytes together in a string for e.g 0 0 0 92 means 9.2ml ?Is there any way to read the decimal point?
VB 8 Program To Communicate With RS232?
Aug 31, 2009I chose Visual Basic 8 as a computer interface to communicate through RS232 (serial) to my microcontroller, which in turn will do its own thing to transmit data it receives from the VB GUI through wireless
I have used VB before but it's been a long time. I looked at some of the settings and it looks like it has a SerialPort com component I can use. Will it suffice for this project?Might be a simple question, but just want some tips from experienced developers.
Communicating Via RS232 - Dll / Delphi Win32 Exe?
Sep 23, 2011I have a Delphi program that communicates with a vb.net dll that I created. The vb.net dll communicates with a Fluke scope meter via an RS232 connection. I have created a program that communicates correctly via RS232, giving me the anticipated value. Though, when I package this up as a dll and access the dll from my Delphi program I always receive a value of "1", rather than the value I was expecting (most cases a value in and around 240).I know that my delphi program is definitely communicating correctly with the dll and that my dll is definitely communicating with the scope meter
Here is my vb.net code:

I am trying to avoid buy any more hardware as this is an objective to acutally cut down on hardware.

Jan 10, 2010I am trying to read a packet of data which has come in from RS232. I need to be monitoring the port until data comes in to be actioned. I have been doing this fine for some time using the following code:
Dim strline As String = Nothing
Dim comPort As SerialPort
Dim bIsOpen As Boolean = False
[Code]....
The code above works without a problem unles byte 1 or two are greater than 127. Basically, all of the characters that are not converted seem to be 128-255.
I am using VB 2008 express. Clearly I need to read each byte individually and store it as a byte within an array instead of a string but i am not sure how to do this.
how to get around this either through reading bytes properly or through using a different encoding format
VB2008 SeiralPort Communication With RS232?
Jun 20, 2010At the moment, I need to write a simple peice of software using VB.
I have a computer with VB2008, a RS232 interface; a electronic scale with RS232 interface; a cable with two female sides(this cable is file transfer cable, it enable data transfer between two computers according to the instruction)
My task is to connect the scale to the computer and the computer will keep track of the data sent from the scale.
how to get started? I'm new to VB and have no background in seiral communication, please give details.
My first question is: I have connected them together with the cable, how can I make sure they are really conected (able to communicate)? And can anybody give a peice of code to let me start building on that?
