Hi!
Thales SIM is HSM simolator, not a host simulator and can not be connected to P3CM (if i understood you correctly) since both of them are servers. What way are you trying to connect to P3CM? If you are writing you software to work with P3CM, you should note that each command must contais SW header, first two bytes of command must contain whole message length in binary representation:
<SW header (2 bytes)><HSM header><Command code><command data>
