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
2
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 
parity:  | n   | 
  | s   | 
  | e   | 
  | o   | 
The default flow and parity control is 
Set the baud rate for the terminal. Defaults to 9600.  | |
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,  | 
  | |
  | terminal, if running as a foreground task, and no terminal,  | 
  | (Phantom), if running as a background task.  | 
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.
