How do I keep Remote Request and Auto Receive from conflicting on one serial port?

Direct answer
Use a reserved program name so DNC-Max can distinguish a request file from a program being uploaded for storage. The reserved number—often something like O9999—must match exactly what the control sends. Otherwise request programs can be saved as uploads and the intended delivery never starts.
Practical checkpoint
Capture the exact request program transmitted by the machine and test the reserved-name match before relying on it in production.
