The problem is with the fork VMMaker.oscog, you need to re-sync SerialPort with the fork VMMaker.

VMMaker-dtl.315 had already the slang methods for the ByName variants, you can copy&paste or directly from Monticello browser replace the methods, then can generate a SerialPort.c with the new functions.

The files platforms/Mac OS/vm/osExports.c and platforms/Cross/plugins/SerialPlugin/SerialPlugin.h need add the new functions, I am attaching this files for your convenience.

Finally link with platforms/unix/plugins/SerialPlugin/sqUnixSerial.c instead of the obsolete platforms/Mac OS/plugins/SerialPlugin/sqMacSerialPort.c.

I tested a VM with this changes and appear to work OK.
