• Java gets serial support with the new javax.comm package
  
  One of the most popular interfaces on a PC is the serial port. This interface allows computers to perform input and output with peripheral devices. Serial interfaces exist for devices such as modems, printers, bar code scanners, smart card readers, PDA interfaces, and so on. Sun's JavaSoft division recently has made available the javax.comm package to add serial support to Java.
