== Synopsis ==
'''Name:''' Silent Link Hook

'''Hook Pointer Block Address:''' [[83Plus:RAM:9BD0|9BD0]]

'''Hook Enable BCALL:''' [[83Plus:BCALLs:50CE|50CE]]

'''Hook Disable BCALL:''' [[83Plus:BCALLs:50D1|50D1]]

'''Hook Call BCALL:''' ''Unknown''

'''Hook Active Flag:''' [[83Plus:Flags:36#Bit_7|7, (iy + 36h)]]

This hook allows you to abort a silent link request.

== Using the Hook ==
The hook only uses the zero flag.
* Zero flag: Clear to abort the silent link request.

== Comments ==
This hook can be used to make sure no silent links interrupt your GetKey call.

== Credits and Contributions ==
* '''Michael Vincent:''' For telling others about this hook.

When you paste code, there is a simple step you can do to format the code properly. Start the first line of code with <nowiki>, and put a space infront of the <. On the last line of your code, end it with </nowiki>. This allows for code to be formatted like this (click edit on this page to see how it's done):

<nowiki>cp 10
ccf
adc a, 30h
daa</nowiki>

83Plus:BCALLs:8090

213.84.152.42:

== Synopsis ==
'''Official Name:''' CalculateMD5

'''BCALL Address:''' 8090

Calculates the MD5 checksum

=== Inputs ===
* BC: The length of the data
* HL: The location of the data

=== Outputs ===
* [[83Plus:RAM:8269|8269]]: Probably changes this, but not tested
* [[83Plus:RAM:8292|8292]]: Will be changed to contain the new md5 (incremental) hash of the data you gave it

=== Destroys ===
Unkown, please add this when you test check this out.

== Comments ==
This B_CALL incrementally changes the md5 "registers" for the data you give it. But it does not add the size word that is required to generate official MD5 hashes, you have to do this yourself if you want official hashes.

== Example ==
<nowiki>B_CALL InitializeMD5
ld bc,0040h
ld hl,SomeAddress
B_CALL CalculateMD5</nowiki>

== Credits and Contributions ==
* '''FloppusMaximus:''' For testing that this B_CALL also work with lengths unequal to 64 bytes

213.84.152.42: /* Example */

== Synopsis ==
'''Official Name:''' InitializeMD5

'''BCALL Address:''' 808D

Initializes the md5 ram area

=== Inputs ===
None

=== Outputs ===
* [[83Plus:RAM:8269|8269]]: 8 bytes will be zero'ed
* [[83Plus:RAM:8292|8292]]: Loads the following bytes in this area 01h,23h,45h,67h,89h,ABh,CDh,EFh,FEh,DCh,BAh,98h,76h,54h,32h,10h

=== Destroys ===
Unkown, please add this when you test check this out.

== Comments ==
This B_CALL initializes the MD5 memory areas so that you can start generating a new MD5 checksum.

== Example ==
<nowiki>B_CALL InitializeMD5
ld bc,0040h
ld hl,SomeAddress
B_CALL CalculateMD5</nowiki>
