View 4 RepliesThere seems to be a lot of discussion around about handling exeptions when a USB serial port device gets unplugged. What I want to know is how can one re-attach to it once it is plugged back in. The problem is that if you unplug a USB serial port device the app doesn't know it has gone and remains convinced it is still open. I have to close the app completely before I can re-attach to the device. I need a way to force it to close/go away.

View 4 RepliesI have a small embedded web server and to setup its network parameters I use a serial port, however this is giving me a lot of trouble due to USB to serial adapters (in some computers work in other doesn't).
However the other day I saw that Buffalo has a little program to find their NAS boxes (or network drives) when you don't know their IP address or got the wrong one so I assume they do it by looking for mac addresses.Is there any way of doing this with VB 2005 or higher? Basically I don't know the IP of the embedded server so I need to find it on a network, how do I find it?
a) I could do a general IP scan assuming it is on the same subnet than the host computer
b) if it has a different subnet... a general IP scan is not going to work, is it?

View 1 RepliesI'm currently working on a project where I am transmitting data from a comm device via the serial port and resorting the raw data (in binary) to its respective ascii values. The problem I'm facing is determining the most efficient method to accomplish my goal. Essentially, I have 68 bytes coming in, the first and second bytes represent the page and packet number and the data itself ranges from 3 to 64, the remaining for my checksum.
What I am needing to do is, grab 50 consecutive bytes per variable in my array, and that is where I'm confused. I have easily pulled my 3-64 bytes and stored that data to a string. I just don't know the most efficient method to accomplish my goal. Should I write directly to file all my data, as there are like 8 pages, of 128 packet data. [Code] I can capture the the first 50 by using a for-loop easily, but what would be the preferred method to track what data chunk I've taken? The more I think about it, I think I may just want to write to file, all my data, and then just take them back to back in 50 byte chunks. Is that the most efficient method?
