NAME in - open and initialize HP-GL
plotter
SYNOPSIS in [m]
[device]
[baud]
DESCRIPTION Without an argument, in
attempts to establish an input-output channel with the name
assigned to the DEVICE parameter in the
$CPLOTHOME/cplot_config or
$HOME/.cplot_init configuration
files. If it is a serial device, the baud rate is
taken from the BAUD parameter.
You can select the device name or baud rate or both by
entering them as arguments after in. Entering
m as an argument opens the HP-GL plotter in
eavesdropping mode, where C-PLOT will try to use
the same line as your terminal for the plotter. This
only works with HP-GL plotters that implement eavesdropping mode
and have been connected to the terminal and computer with a
special Y-cable. Note also there is a D/Y switch on
the plotter that must be in the Y position.
When not using eavesdropping mode, the program treats serial
and GPIB (General Purpose Interface Bus) interfaces
differently. The interface used is established in the
configuration files according to the value of variable
GPIB.
With a serial interface, the program uses ioctl() system
calls to set the baud rate, turn off echoing, turn on XON-XOFF
flow control and so on for the line to the
plotter. The baud rate is taken from the value of
BAUD in the configuration file. When the
device is opened, the program sends out special HP-GL commands to
configure the serial interface on the plotter.
The program does not do anything to configure a GPIB
interface.
