OK; thanks, I get it @toncho11 - Actually on the 386 and unless you have 2 serial ports IRQ3 should be fine, and IRQ5 too unless you have 2 parallell...

@toncho11, This is interesting. What happens when you attempt to make a connection fromELKS is that it sends an ARP request packet. So the arp command should at least show...

Thank you @toncho11, This helps. You card is definitely working, interrupts and all. Also it seems you're receiving packets correctly - since your netstat reports both an ARP cache add...

This is good research @toncho11 - and I agree with you - ARP doesn't seem to work right. However, ELKS ARP is known to work with other interfaces so it's...

Great, thanks @toncho11, that narrows it down quite a bit. So either - the ARP reply packets are not leaving the interface or - the ARP reply packets have errors...

Thanks @ghaerr - the speed is indeed a valid point, and I'll take an extra look at the WD transmit code in the morning. Still @toncho11 - we do need...

@toncho11 , This looks familiar. Try disconnecting all other nodes on the network, so you have only elks and the laptop. ALso change the IP address of the elks system....

@toncho11, @ghaerr, I've looked through the send side of the wd driver. It doesn't look good to be honest - there is a definite danger over overrunning the transmit buffer...

Ok, we're getting there. Can you post ALL output from tcpdump related to the elks machine? Sent, received, broadcast, arp, anything? The timestamps will tell if you had to give...

Thank you, @toncho11 - I'll dive into them first thing in the morning. As to the card, I don't know - but it's unlikely. This is a much newer card...
