#2791 — Announcement: Marina IP June 2016 edition released

For an IP stack that still doesn't actually do anything useful, Marina is
now more capable than ever in the June 2016 edition. ICMP is the name of the
game in this edition, which features enhanced ICMP support to boost RFC
compliance, namely: Marina now replies to ICMP Echo requests (ping!) and
Marina will send a port/destination unreachable message when a foreign host
attempts to send data to a UDP port on Marina that is not open.

The Marina demo is now easier to run because a startup program detects
whether you have an Uthernet or Uthernet II and loads the appropriate
version of Marina! Your network card must be in either slot 2 or slot 3,
however.

For the ultimate in ping response you need to assemble Marina with debug
mode turned off. As it turns out, the Uthernet II is slightly faster than
the original Uthernet. I tested back in April with a Transwarp accelerator,
and got an average ping time of 2.758 ms with the original Uthernet, and a
slightly faster 2.625 ms average with the new Uthernet II. Ping averages
were about 2.7 times slower than without the Transwarp. This is with a
direct cross-over cable connection between a Mac mini with Mac OS X and the
Apple IIe.

Now that Marina will respond to pings, I'd like to get more people testing
Marina in different networking environments.

As usual, the Marina IP web site, user's manual, and Marina Technical
Library have all been updated.

TCP support is still forthcoming, and this edition includes some very small
advancements towards that end. Unfortunately, writing TCP in assembly
language requires a great deal of concentration, and regrettably I can no
longer justify the expense of endless hours in front of the Apple II
keyboard that I once could. Therefore I must announce that, excepting any
compatibility issues brought up through testing Marina in various networking
environments, this will be the last edition of Marina for some time.

If anyone tries to use this, please let me know how it goes-- does the DHCP
work? Can you ping it?

I will fix any incompatibilities here to get it working.
