Having problems with your Dell Latitude D510 Notebook ?

No connectivity via Com Port 1

\015 I am a telephone engineer and I use my laptop to interface with the products I am responsible for at customer sites. Recently I connected to a telephone system to carry out some configuration using Com Port 1 (V24). When I had finished I disconnected as usual. I then had a need to reconnect to the system some 10 minutes later but I could not. I have been unable to connect to anything via Com Port 1 since. All my cables check out ok. I have carried out all the diagnostic cxhecks available on the laptop including the BIOS. They all report that all is ok. Could this be something more basic such as an electrical problem on the interface between the laptops system board and the socket? How can I prove it if it is?\015

Answers :

There is a program called PC Doctor that test computer hardware including com and printer ports. I have an earlier version that runs from a boot floppy. Do a Gogle search for this.
\015\012I also have Checkit, its an old program and runs like PC Doctor and uses a loop back plug which you attach to the com port to test signals in and out of the com port, don't know if it is still available.
You need some way of sending info, you can do this using a loopback plug and some sort of software.

loopback plug is easy to make, you can use Hyperterminal or some testing software (easier to use testing software)

try this freeware test software (page also has loopback plug diagram)
