Syntax for UNIX SVR4.2

ioc.ic_cmd = MIBUFED; ioc.ic_timout = 0; ioc.ic_len = sizeof(int); ioc.ic_dp = (char *)&count; ioctl(moxa_fd, I_STR, &ioc);

Note: Due to the characteristics of STREAMS driver, the returned count of bytes buffered only reflect the data buffered on MOXA board, not including the data buffered in STREAMS queue. In this case, the count is for reference only. For example, returned count may always be zero, but there still are data buffered in STREAMS queue.

2. MOBUFED

This function let you know the byte count queued in output buffer when this function is issued.

Syntax for SCO UNIX/OpenServer

#define MOBUFED 0x402

intcount; /* number of bytes queued in the output buffer */

ioctl(moxa_fd, MOBUFED, &count);
