PC104 RocketPort Option 19
Configuring the Serial Ports
a. Change the communications
mode to match the device you
plan to connect.
b. If necessary, set an Override
and lock baud rate to value.
This option lets you lock
selected ports to specific baud
rates. After you do so, no
matter what baud rate is
selected in a host application,
the actual rate used is the
rate specified here.
c. If necessary, set the Time on
transmit data on port close
value.
Use this drop list to select the length of time to wait for data to clear the
transmit buffer after a host application has closed the port. This is typically
used with peripheral devices such as printers, to give the data sufficient
time to flush through the system.
d. If necessary, select the Map CD to DSR option.
This option is used in installations where there is no connection to the
port’s DSR input. Check this box to cause the CD input to appear as DSR
to the host application, and to perform hardware handshaking with CD
rather than DSR. This is ignored if flow control is not enabled via
IOCTL_SERIAL_SET_HANDFLOW.
e. If necessary, set the Wait on physical transmission before completing write
option.
This option forces all write packets to wait until the transmit data has
physically completed the transmission before returning completion to the
host application. The default mode (box not checked) is to buffer the data in
the transmit hardware buffer, and return completion as soon as the packet
is in the buffer.
f. Select the Clone option if you want to clone all of the ports on the adapter
with the characteristics set in this port.
Note: If this box is not checked, changes apply to the selected port only.
g. Select Ok to make the changes to
the selected port.
If you select 485 as the RS Mode,
this popup appears.
h. Repeat Step 4 for each port that
requires configuration.
