The command is received by an operating system, is socket based and conforms with a standard network communications protocol. The command is forwarded to an intermediate module implemented by code executed on the mobile personal communication device and configured for socket based communication according to the standard network communications protocol. After receiving the command, the intermediate module generates a command communication, for receipt by the peripheral device, according to a protocol specific to the peripheral device. The command communication instructing the peripheral device to perform an operation corresponding to the command. The operation is performed using the peripheral device upon receiving the command communication.
