DELL PRECISION M70 SERIAL PORT

HI,
The serial port of my computer does not work.
I test it using the hyperterminal an jumping the 2 an 3 pins.
In order to have another COM port install a USB-SERIAL adapter but it only works when the utility program is running in windows.
I have 5 old PLC'S that can only be reprogrammed using DOS but i can't enable the communication.

I hope you can explain me what can i do to fix that problem.

PD: Sorry if my english is not very good.

Will windows 7 work on my m70 laptop


Hi

Thank you for your query

Your laptop does have the minimum spec for Windows 7, however I would recommend that you upgrade the memory from 1GB to 2 GB as it will be quite slow.

If you havent already upgraded the memory you currently have is 1 GB 533 MHz DDR2 SDRAM (2 X512MB modules), you will need to upgrade this to 2 X1GB 522MHZ DDR2 SDRAM

I hope this has been helpful.

Dell Precision M70 - Ethernet Port not recognised


if the laptop is wifi enabled there is no need o connect it through the Ethernet cable it will just pick up the signal and you will have to put in the pass code. Even if you want to connect by Ethernet cable you should be able to just plug it in and get on the internet.
if the problem is you don't know the pass code it should be on the original modem manual.

Cajun P333T doesn't accept input from serial


All info from juliankov appears good.. but thought I'd add a bit of stuff I found on a web site..

http://www.tek-tips.com/viewthread.cfm?qid=300461&page=2

Use a console cable with following minimum pinout (the flat gray one with the RJ45- D9 type converter currently shipping with new P33xx switches will suffice): DB9 Console Port
1 ----------- 6
2 ----------- 3
3 ----------- 2
4 ----------- 4
5 ----------- 5
6
7 ----------- 8
8 ----------- 7
9

Obviously the speed is set to 9600
maybe stop all sessions & try to re-establish a new one. The instruction manual warns u can only run one..

Hi. I use the 9 pin port with a Cisco rollover cable to access the console port of routers and switches. Using a terminal emulation program such as HyperTerminal. It allows me to configure the routers and switches. I believe that it can also be used to connect to old modems. I hope this helps, Nelson McKinnon.
