<pre><b>INT F1 - Common ISDN API (CAPI) v1.1 - "API-REGISTER" - INITIALIZE CAPI</b>

	AH = 01h
	ES:BX -&gt; buffer for CAPI's use (refer to note below)
	CX = minimum number of pending messages
	DX = maximum simultaneous Level 3 connections
	SI = maximum concurrent received B3 data blocks
	DI = maximum B3 data block size
Return: AX = CAPI-assigned application ID
	    0000h on error
		BX = error number
		    1001h registration error
Range:	INT 00 to INT FF, selectable by program parameter
Notes:	the caller is required to provide at least 512 bytes of stack space
	the CAPI interrupt handler begins with a header which is nearly
	  identical to the IBM Interrupt Sharing Protocol header
	  (see <a href=../../it/68/25.html>#02568</a> at INT 2D"AMIS"), except that the short jump instruction
	  to a hardware reset handler at offset 09h is replaced by the
	  signature bytes "IA"
	the maximum length of a message is fixed at 180 bytes; the standard
	  document suggests using CX=10, DI=1, SI=7, and DI=130 for
	  applications which use only a single connection and standard
	  protocols
	the total size of the application-provided buffer must be at least
	  180*CX + DX*SI*DI bytes
