Technical Information
This command allows you to set the parameters to values that match
any other RS-232C devices. The receiving side of the driver
is
interrupt driven and contains
an
internal one-character buffer to
prevent loss of characters during disk I/O and other lengthy
operations. The system usually uses the
*CL
devspec to
communicate with the RS-232C port.
If you are using a serial printer,
(1)
use SET to set
*CL
to COM/DVR
(see Appendix
I),
(2)
use SETCOM to set the proper parameters, and
(3) use the command:
ROUTE *
PR
TO
*CL
(ENTER)
to direct output to the RS-232C (rather than the standard parallel
port). Radio Shack printers do not require this procedure since they
use the parallel printer port.
The line condition parameters let you set up the conventions required
by most communicating devices.
The RS-232C line output
parameters are:
DTR =
switch Data Terminal Ready
RTS =
switch Request To Send
The RS-232C line input
parameters are:
1-114
