The NetCharDevEnum and NetCharDevGetInfo functions use the following data
structure when the sLevel parameter is 1:
struct chardev_info_1 {
unsigned char ch1_dev[DEVLEN+1];
unsigned char ch1_pad1;
unsigned short ch1_status;
unsigned char ch1_username[UNLEN+1];
unsigned char ch1_pad2;
unsigned long ch1_time;
};
where:
- ch1_dev is an ASCIIZ string specifying the
device name associated with the serial device.
- ch1_pad1 word-aligns the data structure components.
- ch1_status specifies the status of the device.
ch1_status is defined as follows: 旼컴컴컴쩡컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴커

- ch1_time specifies the number of seconds the
current application has been connected to the serial device.
