RTLinux iz Zentropix 1.0, the sender NIC is Epic100 and the receiver
NIC is 3com 59x (not sure which "x"). I am using stream sockets over
TCP. How can I see if I am (i.e., RTL) having to resend packets?

That's my guess, too, but I can't even get 2Mbps on a 100Mbps LAN :(
The real-time tasks should not be consuming too much CPU.
