AH = 81h DS:DX -> callback routine (see #00657) or 0000h:0000h to disable
Return:
CF clear if successful AH destroyed CF set on error AH = error code (see #00656)
Note: The callback will be invoked on any socket changes whose notification has not been disabled with the status change enable mask; it may be invoked either while processing a hardware interrupt from the adapter or while processing the following Socket Services request
See Also: AH=80h"PCMCIA" - AH=82h"PCMCIA"
(Table 00657) Values PCMCIA callback routine is invoked with:. AL = adapter number. BH = status change interrupt enable mask (see #00658). BL = socket number. DH = current socket status (see #00659). DL = current card status (see #00660)
Return:
All registers preserved
Notes: The callback may be invoked during a hardware interrupt, and may not call on Socket Services. The callback will be invoked once for each socket with a status change
