Yeesh.  Makes that Seiko chip look better all the time, doesn't it?

More to the point, you now have a PIC device that has to have a PC
gateway...  so whatever you're doing, you probably could just as well do
it on the PC to begin with.  It might work OK for a situation where you'd
have a whole BUNCH of PIC based devices all using a common gateway, but I
suspect there's a better way than that.  And it would take a lot of Seiko
chips to equal the cost of a PC and the emWare gateway software, I
suspect.

No, but I'm most of the way through a very basic (read stripped-down)
IP/TCP/UDP/ICMP/SLIP stack for the PIC.  I was using CC5Xfree until I hit
1024+ instructions, and have moved to C2C to see how well it does.  The
code bloats WAY up (1600+ instructions, after manually stripping out a
BUNCH of stuff in the .ASM file).  When it's done, I think it will be a
good fit for a 16C73b or an '87x processor.  Forget about doing it in an
'F84, unfortunately.

I am currently trying to decide what to do about my compiler situation,
since I'm not about to port this to assembler.  I don't think C2C is going
to work well for me, so I'm now looking at CCS, since the cost of entry
for CC5X just went from $90 to well over $200.  This is a hobby project --
albeit a big one -- and I just can't see plowing that kind of money into
it when the dog needs kibbles.
