Information distilled from Norbert's reply to Al. May or may not be correct.

• Chiller will only support Ethernet interface
• Queued commands are a legacy feature that we should not use
• Immediate commands (query and other) act "promptly"
• Text Echo can not be enabled remotely. (My assumption would be that the driver should not use text echo)
• Type C commands are a legacy item and should be avoided
• Commands to set query or set modes happen fast (~100ms)
• GO xxx just take whatever time it takes for the controller to reach that setpoint. (Do we need to use these commands?)
