Im wondering that because it is _not_ directly said in Palm documentation -
correct me if wrong.
At least the connection to external RS232 -peripheral do not work.
Seems that communication functions works :

    portError = SrmOpen( serPortCradleRS232Port, 9600, & serPortID)
    portError = SrmControl ( serPortID, srmCtlSetFlags , &
serialPortFlagsValue, & valueLen );

But the :

    bytes = SrmReceive( serPortID, inbuf, inlen, RCV_TIMEOUT, & errp );

Returns 0x305 ( in errp ), saying that the peripheral do not answer (
timeout ).

This works in m105, m125 and m130, but not in Zire 71.

Any help will be appreciated.

Thanks in advance.
