The 386SWAT debugger was also used in the D3X dos extender (code in PM32 mode). See the SWAT.INC file which can be found in the archive for download from here:

When detecting the presence of 386 SWAT, you must first check whether interrupt 67h is supported and then specify which descriptors in GDT are reserved for this debugger and which descriptors point to interrupts int 01h and 03h in IDT. Then, when you enter protected mode, you can invoke one of these interrupts.

Good luck.
