ROM_GetSerialNumber

ROM_GetSerialNumber()

Returns the unique hardware serial number of a Newton device.

return value

An 8 byte binary object containing the Newton device's serial number.

DISCUSSION

This function is not defined in neither Newton 1.x nor 2.0 OS. You should wrap the call to this function in try...onException block, as in the following example:

 local sn;


try
   sn := call ROM_GetSerialNumber with ()
onException |evt.ex| do
    nil;

if sn then
    // ...

The serial number returned in ROM is not the same as the serial number stamped on the Newton device. The ROM serial number is intended for use by programmers.

The StrHexDump and ExtractByte functions are designed to read binary objects.
