Attn: DOS PC users using EtherSlip for networking:
I have a new version of EtherSlip available that fixes two bugs:
* The incorrect MAC address was being set in the simulated Ethernet header. This broke mTCP NetDrive and possibly other programs.
* The code in EtherSlip that simulates ARP responses has a pointer bug in it. This can cause data corruption or crash your program any time it tries to send an ARP request.
A fixed version can be found at https://www.brutman.com/Device_Drivers/packet_drivers/EtherSlip_v11.8.zip .

Also, please boost the original post ... this is something I want to spread the word about given the possibility of crashes. If you've ever been frustrated by old DOS code randomly crashing before, well, this is one of those bugs that causes that. I'm on a mission to make DOS as stable as possible, one ancient bug fix at a time. ;-0 #retrocomputing #msdos
