If you are not already, I'd recommend that you have the CTCE device defined in the Hercules configuration for both systems, so that they will establish their TCPIP connection when Hercules starts up, and allow VM/370 CP to contact them and issue SIOs to them at system start up so they properly initialize. When both systems are up, then logon to the XNET machines and start XNET.? I often have trouble if I define CTCEs dynamically when Hercules is already up.? I don't think this is a CTCE problem per se; but CP is not initializing the device which helps to establish the TCPIP connection.

Note: there is a small bug in XNET where the last 1 or 2 characters is chopped off the message text if the node id is a longer one, as you may notice above.? It doesnt hurt the operation but you should be aware of it.

Hi Bob,

Sorry for the delayed response.

I have the CTCE connections defined in the configuration file, so they are present at IPL, I have been logging in to XNET while I get this running. I plan to use AUTOLOG from AUTOLOG1 eventually. In trying to properly grok this CTCE/CTCA documentation, I am trying to follow the SDL (4.7) description. What hasn't been clear to me is if I am using an even/odd pair of ports to connect the hosts to each other.

Here are the Hercules configuration entries. First for VM370DEV (line numbers are due to cut & paste from vim)

I would not be surprised if anything related to VM/370 did not chop off characters after character #8. I haven't been able to find out if I can actually use a minus sign (-) in a node name or host id.
