The plug-ins to the C32 Serial Server are known as CSYs (Comms SYstem plug-ins) and they allow configuration of aspects such as: </p> <ul><li id="GUID-14ECCE86-0628-5B10-AA8C-5CF661594A02"><p>the prefix name for the ports. For example, the ECUART CSY ports have the prefix "COMM" while the USB ports have the prefix ECACM" </p> </li> <li id="GUID-BDF2458A-7C43-5E77-8E1D-A7E96B910B94"><p>the actual port numbers the CSY services. For example, by default the ECUART CSY shipped with Symbian OS will accept connections only on ports 0 and 1 ("COMM::0" and "COMM::1") </p> </li> <li id="GUID-81E9969B-D5FE-53D1-AAE7-5F74408B2CC7"><p>the security requirements that a client must meet to access the ports, such as a minimum set of capabilities or a specific process ID, or list of allowed Vendor IDs and Secure IDs. </p> </li> <li id="GUID-0640D1F6-7E47-5FD7-8607-FC73B61AFD6C"><p>the priority of this CSY when it is running in the same thread as other CSYs.
