Using Static IP mode

I don’t use the pd_havelink during initialization either. I monitor what sock_init returns and if I get a 0, I assume the link was made.

When you get to the point of running your program again, break it just before the sock_init call and then step it over just sock_init. If you don’t have a valid link after the call returns then something, as far network configuration, before the call is giving you grief. Besides the TCPCONFIG define and USE_DHCP define the only network thing you do prior to the sock_init call is ifconfig?

I'm sorry, I missed your question. The answer is yes,
I only call sock_init() once.

I have one call to ifconfig() before sock_init() and
one call to ifconfig() after sock_init().

The second ifconfig call is not executed until
pd_havelink() returns true, indicating the Rabbit is
connected to a network. This works fine for DHCP. But
pd_havelink() never returns true when in static IP
mode. So I'm in the process of re-writing my ethernet
initialization procedure to remove the pd_havelink
call when in Static IP mode. I'd don't know if that
will make a difference, but its the only think I can
see that is different between the two modes.

Scott,

    He sets TCPCONFIG to 0 which according to the tcp_config.lib, expects all configuration at runtime. It shouldn’t be giving him problems unless that part of things has changed since my 7.33.

Again, what is TCPCONFIG set to? It should be 6 if you want to configure
manually. Otherwise it will likely override whatever you do. It sounds like
you have it a 0 because.
