Error 68 - Device unavailable

Device unavailable - (%ERR_DEVICEUNAVAILABLE) - You tried to OPEN a device or attach to a device or graphic without that device present or installed.

For example, opening COM1 on a system without a serial adapter or modem, or attempting to use TCP/IP or UDP/IP on a machine without Winsock 2.0 (or better) installed. Also, trying to attach to a graphic or printer that is not available will cause this error.
