serial question - port index?

    May 09 2008 | 12:24 pm
    really quick serial question - the helpfile for the serial object says that the "port" message can take either a letter (a,b,c,d...) or the port name as a symbol - but it doesn't complain when (accidentally) I hooked up an ubumenu and used a numeric index (0,1,2,3...). Is this hidden feature, or is it just ignoring the number and using the first serial port anyway (port a)?
    Thanks, Evan
