Probably these signals are RCMM 32 and 24 bit.  The system code of 38 is typical.  In the IR community, we refer to these signals as Nokia and Nokia32, because they were first seen in devices made by Nokia.  We have assigned arbitrarily device, subdevice, and function numbers as 8 bits each, and the 32 bit version has 8 bits of "X"-- the system code in Philips nomenclature.

So probably these signals can be described as Nokia or Nokia32 with device number 8, and subdevice 240.  The X parameter is 38.  You can generate Pronto Hex by using IrScrutinizer and on the Generate tab select either Nokia or Nokia32 as the IR protocol.  Fill in the D box with 8 and S with 240.  For Nokia32 add X=38 T=0 in the additional parameters box.  Since this is a toggle protocol, you may also need to generate T=1 Pronto Hex also.  For Nokia, omit the X=38.

I'm not sure if the D and S numbers are correct, but these are my best guess. For example:
Nokia32 device 8, sub 240, function 12, X 38 T 0
