infra-red communications, such as to an IrDA-capable printer. See the IrDA
Serial Overview for more information. </p> <p>The example: </p> <ul>

to the Comms server </p> </li>
<li id="GUID-AABB1768-6DD4-589F-9262-213EC3AC90C7"><p>Loads the Comms server
module that supports infra-red (“IrCOMM”) </p> </li>
