: Does anybody have more information on the protocol in use by this serial

pin 2 = TX
    3 = RX
    4 = DTR
    7 = RTS

Normally RTS and DTR are low (-12V), if you set DTR to high (+12V) the 
clock will send ETX. After that you must send 0x01, 0x30, 0xcf, 0x04. 
Than the clock will send the current time: 
   STX 0x07 <7 bytes of data> <checksum> ETX

: I'd like to make it work from within a C(++) module ...

Do you plan the integration into ntpd ?
