Hi Kieran, I´m still working at the problematic that I have to inform from one side of the Ethernet connection to another side that RNR (receive not ready = can not handle more data, please wait) occurs. I thought that I can be use TCP buffer handling and if window size is 0 (in TCP header) than the information will be transported from one to another side.
Currently I see following possibilities: Either I can use different buffer pools (e.g. use PBUF_POOL for data port and PBUF_RAM for control port), Or I can limit the data buffer pool to have at least one buffer for incoming a command at control port which can be handled. Does anybody see another possibilities? Thomas Am 07.04.2011 15:30, schrieb Kieran Mansley: > Not as such.
