com1 not working


Recommended Posts

Posted

My serial port, com1,(DB9) doesn`t seem to work anymore. Computer is a Dell

laptop. I use the serial port to communicate with a MicroChip programmer and

also hyperterminal. I am an electronics hobbyist and use hyperterminal to

setup a few things in an embedded web server in my home. My programmer just

gives message "can`t connect to com1"

Hyperterminal gives message "Another program is using the selected telphony

device. Try again after the other program completes."....How to find what

this "other"device is?

Here`s what happened to make it stop working.

I installed a device(home automation wireless device) called an "X10

FIRECRACKER"

It`s just a 1 inch square device with db9 connectors on each end. It`s

supposed to be "transparent" to other devices. I installed the drivers but

never really tried to use it. I removed the hardware one day to plug my

programmer in and got the message described above. I have uninstalled the X10

drivers, but still nothing works.

I tried uninstalling the com1 port under device manager. After uninstalling

i get message saying i must restart computer. So i do, and look under device

manager and com1 still is installed !

At this point i don`t know what is wrong...hardware is actually broken or

driver is corrupt? Not even sure if i`m in right forum !

How to determine if hardware is "broken" ?

Thank you in advance for anyone who might have any ideas for me.

Mike

Re: com1 not working

 

Can you do a system restore back to before the Firecracker driver was

installed?
