is determined by the expected incoming traffic and the capability of
the host application to process it. If the incoming traffic is bursty,
more input buffers are required. If the application cannot process
incoming traffic fast enough, the input buffer pool will fill up with
unprocessed packets. In that case, the SLTA-10 Adapter will not be
able to pass any new data to the host, and the input application
buffers in the SLTA-10 Adapter will start to fill up. Once that occurs,
messages will be lost, possibly causing incoming LonTalk transactions
to be retried, and eventually causing the sender of the message to
receive a failure indication.

(autobaud disabled), the
autobaud option (IA) does not
need to be enabled.
Sets the serial bit rate to cnnnnnn,. The available serial bit rates are
listed below.
Available serial bit rates are:
1200,2400,9600,14400,19200,38400,57600,115200.
This rate represents the serial bit rate between the PC and the
SLTA-10 Adapter when using a direct serial connection, and between
the PC and the modem when using a remote connection. For remote
connections, the PC-to-modem serial bit rate, telephone line speed,
i.e., modem to modem serial bit rate, and the modem-to-SLTA-10
Adapter serial bit rate may be different. The PC-to-modem serial bit
rate is controlled by the network driver on the PC using the /B
option; the telephone line speed is selected by the modems based on
modem configuration; and the modem-to-SLTA-10 Adapter serial bit
rate is controlled by the hardware configuration of the SLTA-10
Adapter as described in Chapter 4 (autobaud cannot be used in this
configuration).
For local connections with the SLTA-10 Adapter Autobaud option
disabled, the serial bit rate specified by this driver option must match
the rate specified by the configuration switches.
Enables the autobaud feature. This provides the autobaud
sequence whenever the driver is opened. The default setting for
the driver is Autobaud Disabled.
If the Autobaud input on the
SLTA-10 Adapter hardware is enabled, then this option must be
specified. As described in Chapter 4, the default setting for the AB
switch on the SLTA-10 Adapter is disabled, so the /A option does
not need to be specified with the default hardware configuration.
This option may not be used with the modem support (/M) option.
