no worries. I’m on it. got the code from google = “xmodem c#” and it is working reliably over my xbee, albeit slow.
I’m still hunting for the bottleneck and learning some interesting things:
His code seems to accept receiving files at 1k, but only transmits at 128Bytes.
my xbee is running at 57600 and it’s still really slow, but there is only a 100byte buffer on the xbee, so that might play a role.
sending from FEZ to pc has an interesting burst pattern. 5 packets, pause, 3 packets, pause, 5 packets, etc.
Wife’s having a ladies night tonight, so i’ll have more time to dig into it :). I’ll post my progress on the wiki before e/o the day.
At last, I was able to order a Fez from Singapore. but it should have been in my hands since the 29th of May if not because of that &^&%8 clearance delay.

Matt, I’ve found a simple fix about the 128bytes transmit, just go to the startTrans then modify the ff to enable 1k byte transfers.
bufsz = 1024;
xbuff[0] = STX;
BTW, the package seems heavy (5.3kgs), can somebody tell me its contents?
Yeah, I thought the store is in shortage of bubble wraps so they just filled my box with sand. But after sending an email to the store, it seems there was a miss info on fedex’s part. It was supposed to be 113g.
But still… My fez is already 5 days delayed. Sucks to be in a country w/ lazy customs.
Fortunately, there’s no sand. And it weighs maybe a 100g(mostly the weigh of the box).
But unfortunately my device came with 4.0.1
SolutionReleaseInfo.solutionVersion: 4.0.1.0
But my SDK is 4.0.3. And I INSTALLED the DEBUGGING INTERFACE instead of the BOOTLOADER interface, and now tera term doesn’t recognize a new COM port. Now even I uninstall the debug interface, windows will only automatically reinstall it.
Will try to resolve this but will probably try later this evening to my own computer, cause I’m in the office right now.
BTW, is FEZ’s firmware update safe? I really don’t like to mess on a device’s bios or firmware (I’ve killed a PC motherboard through BIOS update back in my slightly younger days).
EDIT:
I still haven’t watched the update VIDEO because my PC here at the office don’t have speakers and I don’t have my earphones now.
EDIT2:
I’ve installed the bootloader driver. Good thing I still watched the firmware update video with no sounds, and I saw that I still need to PRESS the 2 buttons on the domino. I’ve read the FEZ_tutorial but I didn’t understand the HOLD LDR button w/ detach and reattach usb.
TL:DR version:
I had a problem but I managed to solve it.
But I did it on the second try. The first returned a “BAD FIRMWARE” message and a “BL” so I just repeated.
Now I’ll go back to finish my first hello world program in FEZ.
EDIT3:
Deleted EDIT1 and 2. Solved. Sorry Chimp if I use this forum as my Fez diary and posted everything I encounter.
Chimp, It seems you are always MIA at this time of the day/night. And its impossible that you are sleeping/eating so I come to a conclusion that you are Fez-ing right now.
You slept? How can you sleep if you have a Fez? Fez is so FUN. Forget about sleeping, its just a waste of time.
I haven’t slept yet since my Fez arrived. But still did not produce progress. Programming a ConsoleApplication is somewhat different than the WindowsApplication that I been used to.
I’m stuck in just converting a byte array to a string to be output to the debug.print().
string rootDirectory = VolumeInfo.GetVolumes()[0].RootDirectory;
FileStream FileHandle = new FileStream(rootDirectory + @ "\hello.txt", FileMode.Open, FileAccess.Read);
byte[] data = new byte[100];
// write the data and close the file
int read_count = FileHandle.Read(data, 0, data.Length);
FileHandle.Close();Debug.Print("Data from file:");
Debug.Print(data.ToString());
OUTPUT
[quote]The size of data we read is: 32
Data from file:
System.Byte[][/quote]
I have a hello.txt on the USB, the data size is right, but the Debug.Print(data.ToString()); produces “System.Byte[]”.
) and a nice USB cable.
That would still be a funny story to tell to your grandkids one day 
sorry, I will try not to sleep in future
