Mike, I have DECnet running between a number of VAXen on 9600 baud terminal lines. There are a number of things you should take into consideration when you set up the network. If you assume that you don't have the nodes defined in the permanent database you should be able to use the following procedure to get the network up and running. You use the same procedure on both systems, obviously make changes for device names etc. $ MCR SYSGEN SYSGEN> CONNECT NOA0/NOADA SYSGEN> *EXIT* $ SET TERMINAL/PROTO=DDCMP/SPEED=9600 TTxx $ MCR NCP NCP> DEFINE LINE TT-a-b STATE ON NCP> DEFINE CIRCUIT TT-a-b STATE ON NCP> DEFINE NODE 63.1 NAME VMSA NCP> *EXIT* $ @SYS$MANAGER:STARTNET Make sure you do the same things on both systems, and make sure you do it in the correct order. It is very important that you specify the speed in the 'SET TERMINAL' command. Particularly if the previous speed of the terminal line is different than the DECnet speed. Also NCP uses a different format for TERMINAL names than regularly VMS (I think DEC just wanted it to be a little more confusing). The NCP format is TT-number-number. The last number is the same as the normal port number. The middle number is simply the controller - A=0, B=1, C=2 (of-course, real programmers start counting at zero, keep this in mind). An example would be TTB4 = TT-1-4. I had terrible trouble using asynchronous DECnet on non-DEC multiplexors, if you have an Able or Emulex board that doesn't use a standard DEC driver you probably shouldn't bother. One of my systems always went down when everytime I tried an Emulex board with an Emulex supplied UHDRIVER. One last hint. I wouldn't try testing the circuit at 1200 baud. Do it at 9600 or at least 4800. DDCMP is not the most effcient protocol in the world and DECnet may be timing out before a complete packet is sent at a low baud rate. I hope this helps, if you have any more questions let me know. Oh, if you want to get a hold of the Software Tools it should be on the Spring and Fall DECus symposium tapes. == DAG == UUCP - ucbvax!ucsbcsl!darren BITNET - DAG@SBHEP ARPA - dag%sbphy@LBL.ARPA PHYSNET - SBPHY::DAG
