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

I have a need to determine when a string has been completely sent via a serial port from a standard 'C' application. The code is as follows:
SerialPort_Send = open (pPortString, O_WRONLY | O_NOCTTY | O_NONBLOCK);
write (SerialPort_Send, pCommandString, strlen (pCommandString));

Hi,
How can i configure my modem in AIX thru serial port (sa0-->tty0)
I have two port serial card configured as sa0
I created tty1 which port is tty0 and which port is tty1 how can i know?? (1 Reply)
A neighbour's Ubuntu 10.04 machine has five serial ports, one on the motherboard and four on a PCI card. However, only four cards are showing:
# dmesg | grep tty
console enabled

Hi,
I have a external board connected to my serial port. I need to execute "shutdown -r now" command when system boot up. When system boots up it requires a username ans password. Then I need to run my command. I can use rc script but that is rebooting system before it asks for username and... (0 Replies)
Hi Everyone,
In my environment, I have few T5220. On the iLOM Management Card, I have both Network and Serial port are cabled, I don't have any issues while I try to connect using Network Management port, but when I try to connect the serial port for the same server which is actually connected... (3 Replies)

Hello,
I have an unloaded T5140 machine and want to access the ILOM for the first time and subsequently the network port after that., and then load Solaris 10 the final January 2011 build.
The first part is what confuses me -the cabling.
I am coming from a Windows machine (w/appropriate... (5 Replies)

CZ(4) BSD Kernel Interfaces Manual CZ(4)NAME
cz -- Cyclades-Z series multi-port serial adapter device driver
SYNOPSIS
cz* at pci? dev ? function ?
DESCRIPTION
The cz device driver supports the Cyclades-Z series of multi-port serial adapters. The Cyclades-Z is an intelligent serial controller com-
prising:
o PLX9060ES PCI bus interface
o Xilinx XC5204 FPGA
o IDT R3052 MIPS CPU
The MIPS CPU runs firmware provided by the device driver. Communication with the MIPS is performed by modifying data structures located in
board local RAM or host RAM.
The Cyclades-Z comes in three basic flavors:
o Cyclades-8Zo rev. 1 -- This is an older 8-port board with no FPGA. The serial ports are provided by an octopus cable.
o Cyclades-8Zo rev. 2 -- This is the newer 8-port board. The serial ports are provided by an octopus cable.
o Cyclades-Ze -- This is the expandable version of the Cyclades-Z. It uses an HD-50 SCSI cable to connect the board to a 1U rack
mountable serial expansion box. Each box has 16 RJ45 serial ports, and up to 4 boxes may be chained together, for a total of 64
ports. Boxes 3 and 4 require their own external power supply, otherwise the firmware will refuse to start (as it cannot communi-
cate with the UARTs in those boxes).
The Cyclades-Z has several features to improve performance under high serial I/O load:
o The board may operate in interrupt-driven mode or polled mode to reduce interrupt load.
o Each channel has a large input and output buffer.
o Each channel may be programmed to generate an interrupt based on reception of a specific character, e.g. a PPP End-Of-Frame charac-
ter.
o The MIPS CPU on the board performs all flow-control handling.

The cz driver first appeared in NetBSD 1.5.
AUTHORS
The cz driver was written by Jason R. Thorpe <thorpej@zembu.com> and
Bill Studenmund <wrstuden@zembu.com> of Zembu Labs, Inc.
BUGS
The cz driver does not currently implement communication via host RAM. While this may improve performance by reducing the number of PCI mem-
ory space read/write cycles, it is not straightforward to implement with the current bus_dma(9) API.
Interrupt mode has not been tested.
There is no support for reading or writing the EEPROM connected to the PLX PCI bus controller.
