Due to limitations in NdisStallExecution, it is possible that calls to this function of greater than 100 microseconds could cause slower background serial data transmissions to drop characters. For calls of 10 milliseconds or less, Ndis.386 will suspend interrupts on the card by default, regardless of whether or not interrupts were explicitly turned off prior to the call.
Because of these characteristics, do not call this function longer than 100 microseconds. If a wait for a longer period of time is desired, create a timer loop with an NdisStallExecution(100) within the loop.
This functionality will be reevaluated in future versions of Windows 95. Using this technique will guarantee compatibility with any changes in the future.
