Multiple ports remote embedded debugger server
Hai Tao Sun · 2007
This paper describes a study related to multiple ports remote debugger server. Multiple ports remote debugger server supports one parallel port and multiple serial ports. User could connect to target serial port and parallel port from one local workstation or multiple workstations at the same time with serial cables or a parallel cable. All debugger communication ports could receive debug commands from hosts. When a remote debugger server returns data to host machine, it selects a port as a receiver to send out data automatically. If command comes from parallel port host, the parallel debug port will raise an interrupt to a remote debugger server. If a command comes from a serial port, the serial port will raise an interrupt to a remote debugger server. Multiple ports remote debug server is reliable, low cost, portable and efficient.
