Not too shy to talk

@LiveForIt

Each SendIO has to be complemented by a WaitIO.

The sequence is either

DoIo()

or

SendIO()
WaitIO()

or

SendIO()
Wait() or WaitPort()
WaitIO()

WaitIO will not wait if the request is already finished, but it has to be called anyway to clean up the request before it can be reused.

@thomas

Adding WaitIO(), made AbortIO() crash, I guess there are nothing to abort now, maybe a good sign.

60AEEDA0: 0000000A is 10 sec, so that looks fine.
60AEEDA4: 00000000 is 0 micro sec, so that's ok

Most be some thing with the other hex values, I think

ok so io_Command should be 16.
io_flags should be 8 bit
and io_Error should be 8 bit.

Lets se if that fixes, it.

I notice you're using the OldOpenLibrary LVO. If you're testing on OS 4.x that LVO may no longer be valid. It's been deprecated since the new OpenLibrary superseded it in Kickstart 2 or earlier. Passing a zero as the version number parameter to the OpenLibrary LVO does the same thing and is definitely supported.

FYI, OldOpenLibrary() still works on 68K for OS4, but it obviously doesn't exist in the interfaces.

I tried it out for sh*ts and giggles about a year ago.

Well as soon as you remove something, things start to crash, anyway can’t remove any JMP ADR inside jmp table anyway, it will just mess up the LVO offsets.

Just can't stay away

@Samurai_Crow

OldOpenLibrary() is just a stub that calls OpenLibrary(libname, 0) so removing it wouldn't result in much savings and it is needed in the jump table for backwards compatibility.
