Abstract: A host system includes a device driver with application-specific settings for a hosted application. Input data is generated by one or more tablet devices at a client computer system. A host-side data transfer application receives the input data and forwards it to the host-side driver, which sends the input data to the hosted application. The tablet data sent to the hosted application is configured according to application-specific settings of the host-side driver, which may support multiple application programming interfaces. A dedicated driver-to-driver connection may also be used to transmit data between client-side and host-side drivers. In another aspect, a host sends an identifier of a hosted application currently in use to a client-side driver, which uses that identifier to look up and apply application-specific settings to tablet data sent to the hosted application. This can eliminate the need for a host-side driver while still allowing application-specific settings for hosted applications.
