Re: Broken TCP/IP packets

lost its TCP header, but IP header (with protocol type set to TCP) and TCP
payload are still there... We started to see thousands of packets just like
this one somewhere in the middle of 2000, coming from many locations in
Poland.

I have a serial device that is using MCU's UART (rs232) for data
transfer, every time my device is suppose to deliver 20 bytes making
it a single transaction. We have a VB and C# app using MSCOMM and it
works perfectly.
Now I have added an Ethernet converter to convert serial data to TCP/
IP packets. It works atleast for half of the time. For the rest of
the problematic half the behavior is very strange, yes, my received
packets are broken in parts. For example I'll receive 20 bytes in tow
transactions like 10 byte for each time. I tried to look at the MCU
UART signal via oscilloscope but the timing was quite consistent.
Can't understand why packets are broken/scattered, any idea?
