Legend: Some noticeable fields and functions are explained below.
On board TxD buf: The transmit (output) buffer already allocated on the
C218Turbo board for each port. Cannot be altered.
On board RxD buf: The receive (input) buffer already allocated on the
C218Turbo board for each port. Cannot be altered.
External RxD buf: Extra receive (input) buffer you wish to allocate for each
port. This will consume the DOS conventional memory.
Default value is 0.
F5: Group edit: This is a convenient function that helps you edit the
configuration of several ports at one time as a group.
F6: FIFO Setting: This is to set FIFO feature for each port. You can set this
feature to “Enable” (default) and gain best performance
for the board. Or you can set this feature to “Disable” to
avoid from data loss when communicating with
communication devices using S/W flow control.
