Int 1A/AH=82h

PCMCIA Socket Services v1.00 - REGISTER CARD TECHNOLOGY CALLBACK

AH = 82h
DS:DX -> callback routine (see #00661) or 0000h:0000h

Return:
CF clear if successful
AH destroyed
CF set on error
AH = error code (see #00656)

Note: The callback is invoked on a Write Multiple request with an unsupported card technology type

See Also: AH=81h"PCMCIA" - AH=94h



(Table 00661)
Values PCMCIA callback routine is invoked with:.
ES:AX -> Low-Level Socket Services Routines (see #00663).
BH = socket attributes (see #00662).
CX = number of bytes or words to write.
DS:SI -> data buffer to be written.
DX:DI -> 26-bit linear card address.
BP = card technology type

Return:
CF clear if successful
CF set on error
AH = error code (07h,0Ch,12h,14h) (see #00656)

Bitfields for PCMCIA socket attributes:

Bit(s)  Description     (Table 00662)
7-4    reserved (0)
3      packed buffer
2      even bytes only (only valid if 1 set)
1      data width (clear = byte, set = word)
0      memory type (clear = common, set = attribute)

Format of PCMCIA Low-Level Socket Services Routines:

Offset  Size    Description     (Table 00663)
00h    WORD    offset of Write Many routine (see #00664)
02h    WORD    offset of Write One routine (see #00665)
04h    WORD    offset of Read One routine (see #00666)
06h    WORD    offset of Increment Offset routine (see #00667)
08h    WORD    offset of Set Offset routine (see #00668)
0Ah    WORD    offset of Get Status routine (see #00669)


(Table 00664)
Call Write Many routine with:
BH = socket attributes (see #00662)
CX = number of bytes or words to write
DS:SI -> data to be written

Return:
CF clear if successful
CF set on error


(Table 00665)
Call Write One routine with:
AL/AX = data to be written
BH = socket attributes (see #00662)

Return:
CF clear if successful
CF set on error


(Table 00666)
Call Read One routine with:
BH = socket attributes (see #00662)

Return:
CF clear if successful
AL/AX = data read
CF set on error


(Table 00667)
Call Increment Offset routine with:
BH = socket attributes (see #00662)

Return:
CF clear if successful
CF set on error


(Table 00668)
Call Set Offset routine with:
DX:DI = new offset address

Return:
CF clear if successful
CF set on error


(Table 00669)
Call Get Status routine with:
nothing

Return:
AL = current card status (see #00660)
