Driver I
In
order to use the Communications Line device (*CL), you must SET
it to this driver program.
You can use COM/OVR
to
prepare the Communications Line (*CL)
for use.
COM/OVR sets
*CL
to the RS-232C hardware.
After you SET
*CL
to the RS-232C hardware, you can alter the
parameters of the RS-232C port with the SETCOM command.
Example
SET
*CL
TO
COM/DVR
sets
*CL
to its driver program.
SETCOM
(WORD=8,PARITY=OFF)
(ENTER)
configures the RS-232C port using the values specified.
Technical Information
When you set the COM/OVR, it will be placed
in
high memory if there
is not enough room
in
low memory. (Low memory
is
within TRSOOS
and does not take away from the memory available for your
programs.)
If
this happens, a message similar to the following
appears:
Note: driver installed
in
high memory.
If you want to use Memdisk while you are using COM/OVR, be sure
to install Memdisk first.
