BSD, when a terminal file is opened, it normally causes the process to wait until a connection is established. For most hardware, the presence of a connection is indicated by the assertion of the hardware CARRIER DETECT DCD line. This is a problem since most hardware andor cables in common use ignores this line. Using the NONBLOCK flag with open is not enough to get things right, because the DCD is also used to detect the eof condition, causing the channel to assert eof after the first read or gets.

However, this will surely work with one specific USB peripheral chip, namely from FTDI. Resource http www. FTDrivers. htm. They provide a royalty free USB driver. With Tcl apps the virtual com port driver can be used. Advantages over RS 2. USB protocol handles transmission errors, so protocol free communication is possiblehigh speed. I myself created a project with Tcl and USB http www. Jogusto 2. 01. 4 0. Forgive me for saying so, but IMO RJM does not have correct information regarding Advantages over RS 2. The FTDI chip does not do anything for you except create a COM port that your system can use to send serial data via RS 2. So, I think RJM is confused between what USB is, and what the FTDI chip does. USB will not help you communicate over serial if your serial is connecting to a noisy modem channel. Furthermore, the FTDI chip implements the same set of common serial port baud rates available on other hardware implementations eg 1. UARTS. The USB speeds have nothing to do with this. The FTDI chip works very well to add a hardware serial port to a system, if you want to use a USB hardware interface to do it, as opposed to plugging in a PCIe card or something similar. Otherwise, there is really no difference between one kind of serial port, or the other, provided you have the correct driver to present a COMtty device to your OS. That is one thing to be aware of. Many times, especially on older Windows systems XP and previous the USB support wasnt all that great, and in such cases, it is especially important to install the best driver for your system. Some devices simply do not support XP very well, because XP is so old, the USB compatibility with the new device drivers just isnt there. I have upgraded systems running XP to Win 7, and have solved numerous USB compatibility issues, including those with running Serial port bridges over USB. I have also had the experience of having interactions between USB devices with downrev drivers causing problems, where upgrading the driver for, say, a webcam, immediately cleared up issues with the serial port. So, for best results, ensure all your USB devices have up to date drivers for the best results. Those of you still on Windows XP can expect to have problems in certain situationsconfigurations, which you will not be able to solve without upgrading your OS. MS 2. 00. 5 0. 1 0.
