See Makefile for build notes
Written for Keil C51 V5.1 compiler, notes:
It uses big endian order, which is the same as the
network byte order, unlike x86 systems.
Use OPTIMIZE(2)or higher so that automatic variables get shared
// between functions, to stay within the 256 Bytes idata space
This little Program allows you to send commands to the CardReader (CT-BCS) or to the Card itself.
First you will be ask to what Port the Reader is connected (0=COM1, 1=COM2).
Then the Class-Byte (CLA), Instruction-Byte (INS), Parameter 1 (P1), Parameter 2 (P2).
If wou don愒 want to send Parameter 3 (P3) press Ctrl-d (^d).
If you enter a number then you have to the Bytes of the Datafield.
After the last Byte of the Datafield is entered the whole APDU is send the replay is displayed. After that you can send the next APDU.

I ve written some many years ago dynamic Huffman algorithm to compress and decompress data. It is mainly targeted to data with some symbols occuring more often than the rest (e.g. having some data file consisted of 3 different symbols and their total number of occurence in that file s1(1000), s2(200), s3(30) so the total length of file is 1000+200+30=1230 Bytes, it will be encoded assigning one bit to s1 and 2 bits to s2, s3 so the encoded length will be 1*1000+2*(200+30)=1460 bits=182 Bytes). In the best case the file consisted of just one symbol will be encoded with compression ratio as 1:8. Huffman coding is used in image compression, however in JPEG2000 arithmetic codec is imployed.
