Claim:
1. A method of interacting with a field device located in a relatively inaccessible location using an intrinsically-safe handheld field maintenance tool, the method comprising: physically coupling the intrinsically-safe handheld field maintenance tool to the field device via a field device interface that comprises a plurality of wired process communication modules; providing an operating system having an I/O module, wherein the intrinsically-safe handheld field maintenance tool has a local display that is driven, at least in part, by the I/O module; providing wireless communication information from the intrinsically-safe handheld field maintenance tool to a remote device, the wireless communication information being indicative, at least, of alphanumeric display information; receiving the wireless communication information at the remote device and rendering at least an alphanumeric display by the remote device based on the wireless communication information; wherein the intrinsically-safe handheld field maintenance tool is physically coupled to the field device; and receiving the wireless communication information from the remote device and causing the I/O module to inject at least one keystroke based on the received wireless communication information.
