how can I detect the real clockrate of a serial WIC on a 3620
configured as DTE with X.21 DTE Cable ?

If you do a 'show controller' on a physical serial interface, included among the return data should be a line indicating the cable type and received clockrate. Here is an example:
Router#show controller Serial0/0
M4T: show controller:
PAS unit 0, subunit 0, f/w version 1-45, rev ID 0x2800001, version 3
idb = 0x6245AC6C, ds = 0x6245C974, ssb=0x6245CC4C
Clock mux=0x0, ucmd_ctrl=0xC, port_status=0x74
Serial config=0x8, line config=0x200
maxdgram=1608, bufpool=48Kb, 31 particles
DCD=up DSR=up DTR=up RTS=up CTS=up
line state: up
cable type : V.35 DTE cable, received clockrate 56000

this is not the the output of a 3620 with a serial WIC with
a connected X.21 DTE.
