Connecting SUNFIRE V240 to DIGI CM 16


I’m having problems with (2) SUNFIRE V240 servers that just hangs when trying to connect via the DIGI CM 16. I’ve verified the eeprom settings are set to ttya for input-device & output device. I’ve also verified that the cables are good (connected to other existing systems into the same port and it works fine) have looked at the patches, compared /etc/remote files and everything matches up with the systems that work and the 2 that don’t. Any ideas ??
