As an alternative, flow control can be obtained by entering a
numeric option to reflect the desired flow control. This
option is formed by adding together the appropriate numbers
from the table below to provide a more flexible control of
flow.
0 No flow control
1 X-on/off output control
2 X-on/off input control
4 RTS/CTS output control
8 RTS/CTS input control
For example, the default flow control is the number 7
(7 = 1 + 2 + 4 from the table above) for bi-directional
X-ON/OFF and output hardware flow control.
parity: n 8-bit, no parity (default).
s 8-bit, no parity, strip high bit.
e 7-bit, even parity.
o 7-bit, odd parity.
The default flow and parity control is -ryn, or x-on x-off
flow control and 8-bit, no parity.
-s{n} Set the baud rate for the terminal. Defaults to 9600.
-t Set the UNIX terminal device address. This option has a
parameter immediately following giving the UNIX path
name of the terminal to use as the port. For example,
-t/dev/pts01. If not supplied, the default is your local
terminal, if running as a foreground task, and no terminal,
(Phantom), if running as a background task.
-v Alter the default number of virtual memory buffers for this
line. This is followed by a number from 20 to 256. Since
memory requirements for a 256 PICK printer are low,
printer lines should be set to a value of 20 pages.
CAUTION: Altering the default number of virtual memory buffers
for a line increases the true memory requirements of the
system.
