A popular and easy to use program is Putty, which can be downloaded for free from the internet. It is also possible to send commands to the COM port directly from the Command Prompt, but this is for experts only. The symbol represents the port number of the COM port assigned by Windows.
This port must be set correctly in whatever application is trying to communicate through that port. Because older Windows computers only offered COM ports 1 through 4, many legacy applications require the COM port to be set within this range.
Some applications only allow ports 1 or 2 to be set. If the port is out of the range required by the application, you can change the port number by right-clicking on the adapter in Device Manager, selecting Properties, selecting the Port Settings tab, then clicking Advanced.
Device Manager should update and show the number you selected. If it does not, make sure you have sufficient permissions to change the COM port settings. There are many other settings that must be the same for the port and the device being communicated with. Typically the manual for the device being connected will outline the correct settings. Sometimes the application that is used with the device will allow you to change the settings required by the device. Generally, however, the settings for the port are changed to match the settings required by the device.
These settings are changed by right-clicking on the adapter in Device Manager, selecting Properties and selecting the Port Settings tab. The default settings are appropriate for many devices. Data bits, Parity, and Stop bits change the format of the data sent to the device. Typically, if these are set wrong, the device will not be able to understand anything sent to it. Flow control selects a hardware requires a special cable or software method for controlling communications between the devices that keeps their communications synchronized.
Historically, COM ports were used for serial communications with modems, that took the digital information and modulated it for transmission over telephone lines or radio. Information sent from one modem went to the receiver on the other modem, and was forwarded to the receiving pin on the COM port of the destination computer. Which cable to use depends on how the connected device sees itself in relation to the computer. Typically devices that actually do something will require a Null Modem cable, while devices that process data and send it somewhere else like a modem will use a straight cable.
Many devices come with a cable, which should be used if it is available. If the software is compatible, the port settings are made correctly, and the right cable is used, there are still some cases where the device does not work well with a particular USB Serial adapter. Some manufacturers advise against USB serial adapters alltogether or their website or recommend using a particular chipset.
The major alternative available is the FTDI chipset. It is more expensive and works in some situations where the Prolific chipset used in the Plugable serial adapter will not work.
See all Power Devices and Batteries. SATA M. Did anyone ever manage to change the default baud rate of the PL from to Reply 9 months ago. Reply 3 years ago. Everything is working just fine.
However, it turned out, that the default baud rate of the PL is the bottle neck of the system, in case you want to show fast processes. I am not getting your vision. Although changing boud is very simple Everything cannot be given. If you do some practice in project, then only I could help..
Good Luck Dear Rudra Nareayan, Where to get this pcserial. Please provide the link. Samal abhaya tat. Hey, I dont recommend PL, its cheap, but a lot of people have problems with them.

The chip in it is actually a Prolific PL chip. These are the drivers for it. This is the WinXP version.
