Try "COMx 9600,E,8,1"
LM90 is a DOS package. I assume you are using DOS 6.xx to use program. Windows will not allow DOS program to access com ports. Use a VB, C++, etc to access PLC. Be very creative in programming... convert ladder instruction to HEX with checksums.

Good Luck.

Bluetooth Basics ? How it works

Network Topology
Any Bluetooth device can be a master or a slave, depending on the application scenario.
Bluetooth employs frequency hopping spread spectrum (FHSS) to communicate. So in order
for multiple Bluetooth devices to communicate, they must all synchronize to the same
hopping sequence. The master sets the hopping sequence, and the slaves synchronize to the
A piconet is formed by a master and up to seven active slaves. The slaves in a piconet only
communicate with the master.
A scatter net can be formed by linking two or more piconets. When a device is present in
more than one piconet, it must time-share and synchronize to the master of the piconet with
which it is currently communicating.
While the topology and hierarchical structure of WLAN networks are relatively simple,
Bluetooth networks are far more diverse and dynamic. They are constantly being formed,
modified, and dissolved, as Bluetooth devices move in and out of range of one another. And
because different Bluetooth devices can represent many different usage profiles, there are
many different ways in which Bluetooth devices can interact.
Service Discovery
The concept of service discovery is utilized to determine what kind of Bluetooth devices are
present and what services they desire or offer. When a Bluetooth device requires a service, it
begins a discovery process by sending out a query for other Bluetooth devices and the
information needed to establish a connection with them. Once other Bluetooth devices are
found and communication is established, the Service Discovery Protocol (SDP) is utilized to
determine what services are supported and what kinds of connections should be made.
In order for the above to happen, devices willing to connect must be located. Some devices
may be set up so that they are invisible. In this case, they can scan for other Bluetooth
devices, but will not respond if they are likewise queried. Applications determine whether a
device is connectable or discoverable, and thus applications determine the topologies of
networks and their internal hierarchies.

I have error codes flashing on my is an american standard model the manual for the therm. has ACOT900AC43UA on front..says to find addedum 18-HD32D2-1/69-2009 for codes i cannot find it...

Error codes from American Standard Pub 18-HD32D2-8, which is a one-sheet document that came with my American Standard air-conditioner:

29 = not listed

129 = not listed

80 = HPCO Fault - problem is in outdoor unit - Desscription: High Pressure Monitor Fault (hard lock out, cycle power to reset)

91 = Communication Inactive Fault - problem is in air handler - Descriptions - COMM Bit Master Clock Error, COMM Heat/Cool Demand Error, Serial Motor Communication Inactive Error

91 = Communication Fault - problem is in furnace - Descriptions: Blower motor no COMM response, Inducer motor no COMM response, Loss of heat/cool demand, Loss of clock signal

91 = Communication Fault - problem is in outdoor unit - Descriptions: Loss of Heat/Cool Demand Message (COMM), Loss of Bit Master (Clock Signal)

91 = Communication Fault - Description: Comm line is dead and no bits have been received.

By the way, I do not recommend American Standard. I've had mine 14 months and it just blew up - the entire control panel blew. My advice to you - think about a different brand.

Usb to serial converter

1. The USB to Serial has a comm port number, you can change that in Control Panel>Hardware and Software >Device Manager>Click on the adapter and make sure it's not disabled and try COMM 3 or a diffrent port you might have two conflicting each other.

I use Allen-Bradley and I also have to run it as admistrative privleges.

Hope this helps.
