 +  * Older versions of SEXYZ did not support comments on some of the ''sexy.ini'' lines shown above. 
 +  * See ''[[dir:ctrl]]/[[config:sockopts.ini]]'' for the Socket Options that can be set in the ''[SOCKOPTS]'' section. 
 +  * Versions of SEXYZ prior to 3.0 recognized a global ''TCP_NODELAY'' key. Now that key, if it is to be set, must be in the optional ''[SOCKOPTS]'' section (for advanced uses only).

 +===== ZMODEM Streaming =====
 +The ZMODEM protocol supports multiple methods of data streaming and error recovery. SEXYZ supports the following ZMODEM streaming modes, in order of decreasing successful data transfer assurance:
 +
 +  * **Segmented**: a "block at a time" mode, each data subpacket acknowledged by the receiver (whom can request this mode). Can be enabled when sending via the ''-s'' option or by setting ''Streaming=false'' in ''sexyz.ini''.
 +  * **Window Management**: limiting the amount of data "in-flight" between the sender and receiver using asynchronous status reporting by the receiver. Can be controlled when sending via the ''-w'' option or by setting ''MaxWindowSize'' (and optionally ''TargetWindowSize'') in ''sexyz.ini''.
 +  * **Full Streaming**: the default, subject to large send-buffering on the sending side potentially resulting in failed error-recovery or completion-acknowledgment timeouts.
 +
 +//Window Management// mode was added in SEXYZ v3.0 to support very asymmetric send-operations where the sender is a modern system, potentially with multiple-megabyte send-buffers, sending to a receiver that can only consume data at a rate of 115200bps (about 10KBytes/second) or less.
