  1. int iResult1 = open("/dev/ser1",…);
  2. int sock = socket(AF_INET,…);
    Why iResult1 = sock ?
    Is descriptor the global only one ?
    then I close socket through close(sock),but the serail port is closed?
    why?
    thanks in advance.

Hello, eog2000

  1. int iResult1 = open("/dev/ser1",…);
  2. int sock = socket(AF_INET,…);
    Why iResult1 = sock ?
    Is descriptor the global only one ?
    then I close socket through close(sock),but the serail port is closed?
    why?
    thanks in advance.
    is (1) and (2) in different programs, or not?

post more code, please.
