Basic Serial Port Programming
ADR serial data acquisition interfaces require the sending and receiving of ASCII data via RS232 to operate. To communicate with the ADR boards using Visual Basic, the MsComm control must be utilized to allow serial data transfer via a serial port ( Com1-Com4).
Hello,I want to develop an application in VB.Net that captures data (temperature and pressure) using USB port and displays the values on Screen.The values may then be used to generate Graphs or for controlling other devices, again using USB Port.However, I have not found any method in.Net for interfacing with USB Port.How do I proceed?Preetinder SinghDELETED@yahoo.comeditNever post your email address in any forum, unless you really like spam!

Look at what USB stands for: Universal Serial BUS. A USB is not a port, but a BUS, not unlike the expansion slots inside your computer.You interface with the device attached to the port, not the port itself. How you do this depends on what interface the device exposes.
It's entirely possible that the device exposes itself as serial port emulation and you can get at it just like any other serial port device using the SerialPort class.However, if your device doesn't do that, you'll have to get an SDK from the manufacturer of the device to let your code interface with it.

Original Title: Asus notebook and Acer external monitor - resolution unavailable. I have a new Asus UL30A notebook computer and an Acer AL2223W external monitor. I am unable to get the 1680 x 1050 resolution recommended on my external monitor. My computer identifies the external as Generic non-php and will not allow me to update to another driver. I have tried disabling the built in laptop monitor, but still am not given the resolution option I need.
Also, the Intel Graphics Media Accelerator Driver doesn't give me a 'change settings' option. Does anyone have a solution for me?

Hi, What happens when you try to update the driver? Step 1: Check to see if you have the latest Windows Updates installed. Look for the optional updates as it might give the driver updates you want. Step 2: Try unplugging the monitor cable and plugging it back again as it will force a reset and then check for the resolution. Step 3: Update the latest graphics drivers and check for the issue. Also check if there are any chipset drivers available to be updated.
Log on to the computer manufacturer website for the same. Step 4: Uninstall the generic PNP monitor drivers from device manager and scan for hardware changes to check if it picks up the right drivers. Click Start and type devmgmt.msc and then Enter. The Device Manager window opens. Expand Monitors and right click on the external monitor to select Uninstall. Now, click to select your computer as the location for the scan.
On the Action menu, click Scan for hardware changes. Close the Device Manager window and restart the computer. Refer: Also see: Regards, Syed N – Microsoft Support - Visit our and let us know what you think.

Hello everyone. I just purchased a Canvio 3TB External Hard Drive (model HDWC130XK3J1) for use with a pair of MacBook Pro computers (bought circa 2010). I bought this drive because I have another Toshiba HDWC130XK3J1-at least it appears to be identical- that works perfectly with both computers for the last two years.

While the blue light does turn on, neither computer will recognize the new Toshiba drive. I have checked for the drive using the Disk Utility program. In fact, I do not ever hear the hard drive whirring. The old drive still works perfectly with both computers. I have also mixed and matched USB and power cables with no different results. Any suggestions to get this new drive to work?

If it's not even spinning up, then I think you've already identified the problem. It's rare for a Toshiba to fail, but it does happen. Try using the drive on another computer, perhaps a Windows one, and see if it works. Put your ear right up to it and listen to hear if it's spinning up. Could be that the USB to SATA bridge board just cooked from a power surge. It's also worth noting that some externals don't actually spin up until they detect the USB connection. So if the cable or USB port is bad, they don't spin up.
Welcome to the TH Community, Ben! I'd definitely agree with @Jared on this one.
Unfortunately, you might actually be dealing with a faulty external drive since both MacBooks don't detect the device properly. Since it's rather new, you should be able to send it back for RMA and get a replacement from the reseller or from the HDD manufacturer. If swapping the cables didn't help the HDD to be detected in Disk Utility there's not much troubleshooting you can do by yourself.
I'd definitely not take the drive out of its original enclosure as it will void the warranty! Better take it back and get a replacement. Best of luck!
