Hi, I have improved the TFTPClient sample in synapse to support packets bigger then 512 bytes.
The new application works well with 512, 1024, 2048 & 4096 size packets. However when I select 8192 or higher value the client fails. I investigated the issue and found that WaitingData() when called from TBlockSocket.RecvPacket() Will trim any value 8192, and since a TFTP packet of 8192 is actually 8196 in size the system fails. I have multiplied the value returned from WaitingData() by 5 and to my great surprise it works OK for packets upto 32KB. The modified function is attached. Can anyone explain to me why WaitingData() will trim any value to 8KB? Regards, Itzik Mintz
