you should not have to do this but *cls is supposed to clear out anything in the output queue

If you hold down the toggle and sweep buttons while powering on there will be a secret menu to set the correct model. Menu->General->Secret
 

TSP-Link cables need to be cross-over cables

So the command "SOUR:SWE:VOLT:LIN" 1, 5, 10, 0.1, 1, Best, Off, ON "will create a source configList that increases from 1V to 5V in 10 increments and then because dual setting is on it will add to the configlist from 10 down to 1V. The trigger flow it creates simply loops through this configlist and at end of each loop it does a config_next.
Basically the command you are using creates the configlist. You just need to modify the trigger model it creates to add a delay block after the sweep forward has completed so the config next block, after the delay, would start the first backward sweep.

Read the Trigger Flow section of the manual to learn about this and view the trigger flow that is created in the instrument through the front panel. Then you need to create your own flow, pretty much like the instrument has done but add a delay block to start the backward sweep.

See attached example trigger flow

So you need to build a trigger model in the instrument using the trigger flow. After running the seep once press Trigger -> Configure on front panel. You should see a trigger flow and you can insert your delay between sweeps in the right place. Just try through front panel for now and then move back to your program and add the commands to modify the trigger model
 

What instrument are you using?
