In Icc240d5c8c04198640eb118565ea99f10ba27466 we introduced support for writing files > 255 bytes by splitting the write into multiple chunks. However, at the same time, that commit broke support for writing data at non-zero offsets. Unfortunately, this is used extensively within pySim-prog e.g. for writing K + OP/OPc data to sysmoISIM-SJA2 and sysmoUSIM-SJS1 cards. This commit fixes the related problem. Change-Id: Ie1aeaab29701946233ed73db3331039690d695da Fixes: Icc240d5c8c04198640eb118565ea99f10ba27466 Closes: OS#5254
pySim - Read, Write and Browse Programmable SIM/USIM Cards
This repository contains Python programs that can be used to read, program (write) and browse certain fields/parameters on so-called programmable SIM/USIM cards.
Such SIM/USIM cards are special cards, which - unlike those issued by regular commercial operators - come with the kind of keys that allow you to write the files/fields that normally only an operator can program.
This is useful particularly if you are running your own cellular network, and want to issue your own SIM/USIM cards for that network.

Usage Examples
- Program customizable SIMs. Two modes are possible:
- one where you specify every parameter manually:
./pySim-prog.py -n 26C3 -c 49 -x 262 -y 42 -i <IMSI> -s <ICCID>
- one where they are generated from some minimal set:
./pySim-prog.py -n 26C3 -c 49 -x 262 -y 42 -z <random_string_of_choice> -j <card_num>
With <random_string_of_choice> and <card_num>, the soft will generate
'predictable' IMSI and ICCID, so make sure you choose them so as not to
conflict with anyone. (for e.g. your name as <random_string_of_choice> and
0 1 2 ... for <card num>).
You also need to enter some parameters to select the device:
-t TYPE : type of card (supersim, magicsim, fakemagicsim or try auto)
-d DEV : Serial port device (default /dev/ttyUSB0)
-b BAUD : Baudrate (default 9600)
- Interact with SIMs from a python interactive shell (e.g. ipython):
from pySim.transport.serial import SerialSimLink
from pySim.commands import SimCardCommands
sl = SerialSimLink(device='/dev/ttyUSB0', baudrate=9600)
sc = SimCardCommands(sl)
sl.wait_for_card()
# Print IMSI
print(sc.read_binary(['3f00', '7f20', '6f07']))
# Run A3/A8
print(sc.run_gsm('00112233445566778899aabbccddeeff'))
