Parameter

 * /S&#58;sss
 * Specifies the number of streams that can be created at the same time. Values range from 1 through 64. The default value for machines with more than 8MB of memory is 12. The default value for machines with 8MB of memory or less is 6.


 * /P&#58;ppp
 * Specifies the number of processes that can create streams at the same time. Values range from 1 through 64. The default value for machines with more than 8MB of memory is 12. The default value for machines with 8MB of memory or less is 6.


 * /H&#58;hhh
 * Specifies the maximum amount of heap space (KB) that will be used. Values range from 16 through 256; the default value is 64.


 * /Q&#58;qqq
 * Specifies the size of the event queue (per process). Values range from 2 through 1024; the default value is 64.


 * /E&#58;eee
 * Specifies the number of events that can be enabled (per stream). Values range from 1 through 1024. The default value for machines with more than 8MB of memory is 32. The default value for machines with 8MB of memory or less is 20.

NOTE: The DEVICE=SSMDD.SYS statement must appear as the first Ring 0 stream handler statement in CONFIG.SYS.
