<p><b>Range:</b><br>INT 00 to INT FF, selectable by program parameter

<p><b>Notes:</b>
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

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
