What is hcxStuDefCom21SwImage?

This read-write DisplayString (16 bytes), null by default meaning no default image, specifies the software image loaded onto a Com21 modem that has been acquired but not yet configured or authorized. It ensures new Com21-branded modems boot with a known baseline firmware automatically. For example, an admin sets this to "com21_def.img" so freshly acquired Com21 units come up on a verified default image before individual customization.
