Com port and RS-232C

I have an old nordson controller that drives a mechanical insertion unit for
the factory floor. An older software helps the controller communicate through
com ports. It's running fine with windows 98, but were trying to upgrade all
units to XP and it won't talk to each other.

The problem is, XP is not allowing the unit to control its own operation.
There are DTR handshake issues that XP, due to more security, has with
talking to the controller. Is there a way to set XP DTR com port high, to
match that of the default for the software?

If anyone can point me to a direction of how to get through this, I would
greatly appreciate it.

Thanks in advance for any input,

Noel

Don't know if this is what you have in mind but try the "MODE" command
at the command line.

MODE /? for usage/parameters

The problem is, there is no interaction between the two hardwares, the host
(my comp) and the controller. I don't think the RS-232C is wired correctly
for it to work. The problem is, I'm not sure if and how I can rewire for it
to work.

Thanks again for the help,

Noel

I do not know if yo do or don't have a wiring problem. The serial port pin
out is fairly standard, and the active pins are usually those needed with
any sort of "standard" modem.
As far as serial port utilities, Hyper Term can be used to send ascii data.
Options should allow you to see what reply information is sent by the
device.

Unfortunately, I tired using Hyper Terminal, but the units did not respond.
It seems that the controller is wanting control of the machine without having
to get permission from the host. Since the host is XP, they are clashing.

I just hoped there was a way to change XP or the wiring of the handshake pin
so it will allow the controller to take over.

Thanks for the help,
