AT_Slave example only accept first AT command

[peterj43]

When using the AT_slave example I found that I would only get a response to the first AT command I sent. I am working with version 1.2.3 but don't think the issue is only in this version.
I have debugged the issue and believe the issue is in command.c CMD_Process(void)

void CMD_Process(void)
{
  static char command[CMD_SIZE];
  static unsigned i = 0;                                 // This should not be declared as "static" 

  /* Process all commands */
  while (IsNewCharReceived() == SET)
  {
    command[i] = GetNewChar();

#if 0 /* echo On    */
    PRINTF("%c", command[i]);
#endif

    if (command[i] == AT_ERROR_RX_CHAR)
    {
      i = 0;
      com_error(AT_RX_ERROR);
      break;
    }
