Getting the IPL speed

 

To find out the system initial program load (IPL) speed, you can use the GetIPLSpeed API (use the uppercase and lowercase shown).

There are no restrictions to the use of this command.

This API returns the following information:

Bytes 0 and 1	Bytes 2 and 3	Bytes 4 through 4+N
16-bit return code 0 = Command successful 1 = Command unsuccessful	16-bit additional data length N N = size of ASCII return value (does not count end of string NULL)	Slow/Fast or V=Slow/V=Fast The responses with V=Slow/V=Fast indicate the default IPL speed.
