BR, Mikko Dear Sir, Dear Sir, Thanks!!! Its working now. Negotiated Max PDU size should be less than negotiated server max TX RX lenght in SNRM UA BR, AP Hi, Hi, If Negotiated Max PDU must be smaller than the maximum frame size in SNRM UA then the PDU must fit to one frame. That is not a problem if you have a lot of RAM. BR, Mikko
