AWK-1121/1127 Software Installation and Configuration
4-12
8. Click the Advanced Setting tab to modify Tx Mode, FIFO, Fast Flush, and other parameters.
Tx Mode
Hi-Performance is the default for Tx mode. After the driver sends data to the AWK-1127 , the driver
immediately issues a “Tx Empty” response to the program. Under Classical mode, the driver will not send
the “Tx Empty” response until after confirmation is received from the AWK-1127 ’s serial port. This causes
lower throughput. Classical mode is recommended if you want to ensure that all data is sent out before
further processing.
FIFO
If FIFO is Disabled, the AWK-1127 will transmit one byte at a time when the Tx FIFO becomes empty, and
an Rx interrupt will be generated for each incoming byte. This will result in a faster response and lower
throughput.
Network Timeout
You can use this option to prevent blocking if the target OnCell is unavailable.
Auto Network Re-Connection
With this option enabled, the driver will repeatedly attempt to re-establish the TCP connection if the
AWK-1127 does not respond to background “check alive” packets.
Return error if network is unavailable
If this option is disabled, the driver will not return any error even when a connection cannot be established
to the AWK-1127. With this option enabled, calling the Win32 Comm function will result in the error return
code “STATUS_NETWORK_UNREACHABLE” when a connection cannot be established to the AWK-1127.
This usually means that your host’s network connection is down, perhaps due to a cable being disconnected.
