PSIKOTIK TSO User Enumerator. A fast TSO user enumerator written in straight python without the need for s3270 or x3270.

It should mostly work on any mainframe. If it doesn't get to the TSO logon screen then you need to sniff a real connection to the mainframe and find out what the hex stream looks like when you type 'TSO1' (for example) and change tso_command to reflect that value.
