1. A mobile client computer comprising:
- a housing sized to be held and manipulated by the hand of a user;
memory mounted within said housing and storing digital data;
a central processing unit mounted within said housing and coupled to said memory;
an input/output controller mounted within said housing and coupled to said central processing unit;
a plurality of input/output ports coupled to said input/output controller, each of said plurality of ports defining a general purpose input/output interface; and
a display mounted in said housing and coupled to said central processing unit and said memory and displaying information derived from digital data processed by said central processing unit;
said ports and said input/output controller and said central processing unit cooperating in (1) detecting the presence of an optional radio transceiver device if connected to said ports and (2) querying such radio transceiver device using said ports for an encoded identification in one of alternative data formats, wherein said one of alternative data formats is a fixed bit pattern presented at the ports and the other is a bit sequence downloaded over the ports from a storage, and (3) determining from any response returned the identity and characteristics of the radio transceiver device.

Abstract
A computer, and particularly a mobile client computer system, in which flexibility in use of the system is enhanced by a capability of receiving and dynamically recognizing a variety of what are here called docking options. Docking options are peripheral devices, such as radio transceivers, which can be selectively connected to and used with a mobile client system. A docked option is identified by an exchange of signals between the system and the option, accomplished through a plurality of input/output ports which together define an interface to the option.
