Reading Ethernet Port Pins

Jun 10, 2011

[code]Through these ports I have been able to connect simple press-button triggers (or switches) and programatically "read" them. i.e. tell when they are open or closed, grounded to earth or not.With modern PCs I am now somewhat limited. I can still use the MIC port and USB port (when connected to a USB/Serial cable) but since WiFi, my ethernet port is now "available". If you've read this far, you already know my question. How can I "read" the ethernet port pins. I realize that perhaps not all the pins may be simply read, but perhaps one or two at least.

Reading The Ethernet Port Pins?

In the past I have been able to simply read the physical pinouts on the:

Games Port (DB15) (using PEEKS and POKES)
Parallel Port (DB25) (also using PEEK and POKES(888))

Write Directly To Ethernet Port?

Feb 7, 2011

I am writing an app that does part of what another app does (I have no access to the source for the other app other than to see Wireshark output.)

I need to send a broadcast over the LAN and then parse the results. However, the sending of the broadcast seems to be code that is direct to the LAN connection, as in it doesn't seem to write to a standard IP/port combo.

I see apps like Raw Ether that do this at a cost of hundreds of dollars.

Is there some way to not have to buy 3rd party stuff to do this in VS2011 w/ VB.net?

How To Read Text From TCP Port

Apr 10, 2011

I have a device that is continuously sending text over a TCP port and I want to write a VB.net application that will read and evaluate this data. Being new to programming I am having trouble working out how to establish a connection to this TCP port and read the text using VB code. I am able to view this stream of data using telnet.

Most of the example code I have seen during my research seems to deal with two way communication but I think what I need is just one way (I don't need to send any commands to the device - just read what it is sending). I'm hoping some kind person can provide example code to get me started or point me in the right direction?

Read / Write Data From RS232 Port?

Aug 23, 2010

I need to write and read data from a RS232 port. On the RS232 port there is a RFID Card reader-Writer connected. So I need to send hex codes to the device, and have to poll every 1sec if there is a card in the system. If there is a card I need to read the info that is on the card. My biggest problem is I think is that I am not sure how many characters there will be in return after the read command (maybe it is always the same length this I am not sure). What is the right way to read-write to the com port. So I always got the same result and not skipping a code.

Cannot Correctly Read Bytes From Serial Port Consistently

Jun 4, 2009

I have a timer control that sends data to a hardware every 3 seconds. I sent 6 bytes of data. In return  I am expecting 8 bytes of data in DataReceived event. First time I send 6 bytes of date, in DataReceived event, I get the expected 8 bytes. Then in next 3 seconds, again the expected 8 bytes of data is received. But after that I find that DataReceived is fired 2 times: first time I get 6 bytes and then I get 2 bytes. After that I again get 8 bytes as expected. So in short, 2 times I get 8 bytes as expected and 6 bytes and 2 bytes and again 8 bytes. This pattern is repeating continuously. Why? Is there any reason why I cannot get all 8 bytes everytime? Note that the code is in vb.net 2008

Code in button btn_Start () 
'Set serial port parameters
x.PortName = "COM1"
