Looks like I can use that as the go-between. MRC with the help of Stu Grosman did a phase 4 port to KS tops20. It uses teh KMC/DUP, but has a limitation, as there was not enough memory left, all buffers had to be in one page, the decnet MTU is not 576 but 376 or something like that. This does not matter unless you have two interfaces and try to be a transit node. (it can be routein-iv). Any idea where I can find this Phase IV port? It speaks DDCMP on the CYNC interface, so anything that speaks DDCMP can talk to it, DUP,DQ, DMC DMR ... -P -- Cory Smelosky http://gewt.net Personal stuff http://gimme-sympathy.org Projects
