There is one key issue with your configuration:

As soon as you specifically set a device address or vector you implicitly disable auto configuration of all device addresses and vectors.  So early in your configuration you set an address for the RQ device.  The address you set is the default auto-configuration address for the first MSCP controller so that isn't necessary.  Leave out that line.  Your second MSCP controller is not at the auto-configuration address for a secondary MSCP controller, so that will have to be handled separately (move device setup for devices with non-standard addresses to the end of your configuration).  The TS device is at the default auto-configuration address (and vector) so merely enable the device and DON'T set any address.  The RY device is at a non-standard auto-configuration address so move that section to the end of the configuration.  The LPT device is at the standard auto-configuration address for the first LPT device, so don't set address and vectors for this device.

The below configuration reflects what I said above.  Meanwhile what issues with the SIMH serial line implementation are a problem?
