To have your program find out the system IPL speed, use the API GetIPLSpeed (use the uppercase and lowercase shown).
There are no restrictions on 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 or Fast or V=Slow or V=Fast NOTE: The responses with "V=" indicate the default IPL speed. |
