Q1:ISO8583 structure problem
ISO8583 is the structure : msg-len+TPDU+MSG
I test your module. I do not find it(TPDU).
Q2: ISO8583 sending message:
1.msg_len is nible type
2.MTI is nible type also. e.g MTI='0200'
3.F41/F42 is char type.e.g F41='12345678'
So,After the step ,message = iso.getNetworkISO().
If I use binascii.b2a_hex(message),
MTI is 0200, F41 should be 31323435363738.

Hi,
About Question 1:
By default ISO8583 ASCII TCP/IP dosen't have TPDU.
If you want to add this funcionality, you can work with "getRawIso" and
build your
msg-len+TPDU+rawIso
About Question 2:
ISO8583py only work with ASCII ISO8583.
If you see a "number" inside the bit, it will be interpreted as ASCII. By
example, 1
is \x31 always.
Please read the documentation in
http://www.vulcanno.com.br/python/ISO8583.ISO8583.html to see details.
The method binascii.b2a_hex(): "Return the hexadecimal representation of
the binary
data."
(http://docs.activestate.com/activepython/3.1/python/library/binascii.html)
but ISO8583 is ASCII and not binary.... So this use was not correct.
