Is there a magical com port address to create a connection interface, such as with"comm:com2;baudrate=4800") ?

There must be some kind of a document to display all url addresses for datagram, comm ports, sms, mms, sockets etc..

I see magical numbers such as "datagram://:60533" or "sms:/:6532" or "sms://:5432".

system.getproperty( "microedition.commports" ) does not function at the device. Is there one that functions?

Appreciate your help very much!
