Yep - the MSDN documentation file is a .CHM; you can look under MSComm Control and Using the Communications Control in the index tab of the MSDN library.

MSCOMM is a low-level port manipulation abstraction of serial comms; if you are expecting to find file-level concepts, like single simple statements that send or receive a file, support of various transfer protocols and the like, MSCOMM is not a solution for you. It sends and receives low-level streams of data.
