So you have a scale local to you that you can see and physically connect to? Correct
This would have to be connected to the serial port using a cable then? Yes? Correct
Does the scale require a Null Modem Cable or an Extension type? NO
The data I displayed was after connecting the scale to the computer with a serial cable.
Assuming the scale has RS232 transfer; what are the serial parameters


Code:
     | Comp| A -    Serial Device      : /dev/ttyS0                                |                                               |     B - Lockfile Location     : /var/lock                                 |                                  
    | C -   Callin Program      :                                           |                                  
    | D -  Callout Program      :                                           |                                  
    | E -    Bps/Par/Bits       : 9600 7E1                                  |                                  
    | F - Hardware Flow Control : Yes                                       |                                  
    | G - Software Flow Control : No                                        |

Can it be used in raw data transfer mode? Please Explain

iscc(7) 						 Miscellaneous Information Manual						   iscc(7)

NAME

       iscc - serial communications interface

SYNOPSIS

       controller  iscc0  at  isa0

DESCRIPTION

       An  onboard  Zilog  8530  DUART	provides  AXPvme-based Single Board Computers with console (CON) and auxiliary (AUX) serial communications
       ports.  Both serial communications ports can operate at baud rates from B50 to B38400,  excluding B134 (see tty(7)).

       On AXPvme Single Board Computers configured with a graphics head as the system console, the CON serial communications port (/dev/tty01)	is
       available for use by application programs as an additional communications port.

       In  the	absence  of a graphics head, the CON serial communications port (/dev/console) becomes the system console. When used as the serial
       system console, the CON serial communications port always operates at 9600 BPS, 8-bits, and no parity.

       Regardless of system console, the AUX serial communications port (/dev/tty00) is always available for use by application programs.

RESTRICTIONS

       Data communications equipment attached to the CON serial communications port must be set to 9600 BPS, 8-bits, no parity when configured	as
       the serial system console. The iscc terminal driver enforces this restriction.

       No modem control is supported for either the CON or AUX serial communications ports.

FILES

       console terminal local terminal local terminal
