3.2.2 Set Buffer Size
If applicable to your protocol, you can set the buffer size in the DLI configuration file
port definition section as in the following example:
BufferSize = 256;
On some protocols the following format is used instead:
MsgBlkSize = 256;
The DLI will send the Buffer Size command to the ICP as the first command after the
Attach command. The Buffer Size applies to all links on the ICP, therefore, the first
Buffer Size command sent to the ICP sets the buffer size for the entire board until the
ICP is reset or reloaded.
3.2.3 Enable Link
By default, DLI automatically enables the links at session start. If you do not want DLI
to enable the link at session start, place the following line in the port definition section
of the DLI configuration file:
enable = “no”;
3.2.4 Local Acks
Local Acks are packets sent from the protocol software on the ICP in response to data
packets send by the SRA or client program. Local Acks are indications that each data
packet that the client program sent to the ICP has or has not been successfully transmit-
ted on the serial line. The default mode in Normal operation is the for the DLI to auto-
matically handle Local Ack packets. That is, the DLI will intercept Local Ack packets and
match them to outgoing data packets.
