usb to rs232 converter

I can't get my usb to rs232 cable to install and vista keeps indexin
the com port as it trys the next install. I have downloaded the driver
updated the driver, deleted the driver and reloaded the driver to n
avail. Now it shows 26 com ports in use and tells me the device I a
trying to install is trying to use a display name that is already i
use. How do I clear this up so I can install this device

Sounds like the driver software is buggy. Another possibility has to do with
BIOS settings that relate to com ports.
(I haven't run across this problem in a long time.) It used to occur
occasionally when i/o cards/devices used a com port, and did not meet the
P&P specs.

there is also a thing called straight cable on a usb to seria

or null cable on a usb to serial. certaing new cables do accept vist
and some older ones dont.

depending on what your trying to do. it will read it if its the wron
or right cabl
but wont work unless on the other end accepts null or straight type o
cable

i recently had the same problem when i was using a null usb to seria
cable made by prolictic which the null has different pins to it than th
straight; from end to end

i don't thinks its a bios issue if your I/O's com ports are good i
device manage

then it should work with the right cable

i used it on a fta box just a serial to serial worked on straight no
nul

and other use null. it all depends on two things you device is workin
on device manager. and the cable on the other han

what are u using it by the wa

From an elevated command prompt, type set
devmgr_show_nonpresent_devices=1, press enter, then type start
devmgmt.msc and press enter.

From the Device Manager, select View - Show Hidden Devices. Now when
you expand the COM ports section you will see all of the old devices and
can uninstall them.
