What is hcxStuDef3ComSwImage?

This read-write DisplayString (16 bytes), null by default, specifies the default software image assigned to an acquired but unconfigured or unauthorized 3COM modem. It serves the same purpose as the Com21 default-image attribute but targets the different vendor's hardware. For example, an admin sets this to "3com_def.img" so newly discovered 3COM-branded cable modems automatically receive a supported baseline firmware.
