"easy" Way To Interface With The Parallel Port?
Sep 16, 2011I have a problem interfacing with the Parallel Port. I have tried using the "inpout32.dll" to communicate with the port, but it didn't work for me. I have used another program (coded in C++), and I have successfully read the S-port-data - and that's what I mainly need the application for.

View 4 RepliesUnable To Close Serial Port After USB / Serial Converter Disconnected
Mar 28, 2006I have a stand alone VB.Net 2005 application that uses a serial port that generally stays open while the application runs on a Windows XP system. In trying to bullet-proof the UI, I ran into a problem when the USB to Serial Converter normally used to provide the serial port is disconnected while the serial port is open. In trying to handle the resulting error when accessing the port, I find I cannot close the port.
When trying to do so, the error message says something like "unable to close the port. You may not have sufficient permissions." Reconnecting the USB/Serial Converter does not reactivate the port.

View 5 RepliesVS 2010 Writing To Parallel Port / Windows 7 64-bit
Mar 11, 2011Does anyone have experience writing data to the parallel port (printer port) in Windows 7 64-bit. I have been trying inpout32.dll, inpoutx64.dll and following all the info on http://www.highrez.co.uk/ and www.logix4u.net but can't get anything to work. I have an on-board parallel port at &H378 - not an add-on card - and have tried various modes in the BIOS (standard, ECP etc). I have a background in electronics so I am confident my testing methods are sound; I just cannot get a data bit to change state under program control. I need to send data to an 8-bit port on some 20th Century electronics so serial/USB interfaces are not really an option. There must be a way to control those 8 data bits in Windows 7, mustn't there?
View 14 RepliesWriting A String To LPT1, The Parallel Port?
Dec 18, 2011I have a fairly old radio receiver. (Icom R70) A friend and I have built an interface to control it from my computer. The interface is parallel. For me the interface is a black box. (My friend is the electronics specialist) In the description (25 years or more old) the statement to set a frequency and receive mode (like Am, FM etc) on the receiver is:print ".0:087330"
Today I am working in VB.Net and on Windows7 pro. I have already spent several days figuring out how to do this, but can't get it to work.I have found inpout.dll, but that does only allows me to write one byte at the time, and if I break up the above string and send nine individual characters, it does not work.

I can get it to read the state of the input on mouse click but i need it to display the time in micro seconds when the input changes. i will then use the times from the two sensors to work out the time it took between both sensor changing.
