This enhancement has been incorporated in Release 2009a (R2009a). For previous product releases, read below for any possible workarounds:
The ability to use the SERIAL function is not available on 64-bit Linux platforms with MATLAB.
To work around this issue you could write a MEX-file to access the serial port.
We have verified that there is a bug in MATLAB 7.0.1 in the text of the error message that appears. The error message does not distinguish between 32-bit and 64-bit versions of Linux. This error message has been fixed in Release 14 Service Pack 3 (R14SP3).
