A USB-to-serial adapter or simply USB adapter is a type of protocol converter that is used for converting USB data signals to and from serial communications standards (serial ports). Most commonly the USB data signals are converted to either RS-232 , RS-485 , RS-422 , or TTL-level UART serial data.
The TRS-80 series of computers were sold via Radio Shack & Tandy dealers in North America and Europe in the early 1980s. Much software was developed for these computers, particularly the relatively successful Color Computer I, II & III models, which were designed for both home office and entertainment (gaming) uses.
Open Host Controller Interface (OHCI) [1] is an open standard.. Die shot of a VIA VT6307 Integrated Host Controller used for IEEE 1394A communication. When applied to an IEEE 1394 (also known as FireWire; i.LINK or Lynx) card, OHCI means that the card supports a standard interface to the PC and can be used by the OHCI IEEE 1394 drivers that come with all modern operating systems.
Under TRSDOS 6.x, COMM/CMD is a terminal program that establishes communications between the Model 4's RS-232C serial port and that of another computer, a modem or serial printer/plotter. Must first install the driver for the serial port, COM/DVR using the SET command, which establishes the system *CL (Comm Line) device.
Drivers that may be vulnerable include those for WiFi and Bluetooth, [19] [20] gaming/graphics drivers, [21] and drivers for printers. [ 22 ] There is a lack of effective kernel vulnerability detection tools, especially for closed-source OSes such as Microsoft Windows [ 23 ] where the source code of the device drivers is mostly proprietary and ...
MacUpdate has offered several "bundles" offering Mac software at a discounted price. [2] [3] [4] The company offered an application called MacUpdate Desktop ($20/year with a 10 day trial) which automatically downloaded and installed updates to other installed applications on a user's Mac. [5] MacUpdate Desktop has since been discontinued. [6]
Additional memory and serial port expansion options were available from aftermarket companies. The Model 6000 was referred to simply as the Tandy 6000 due to a marketing decision to move away from the Radio Shack and TRS-80 badges. The 16B was the most popular Unix computer in 1984, with almost 40,000 units sold. [30]
With a vendor-supplied INF file, Windows Vista works with USB CDC and USB WMCDC devices. [1] This class can be used for industrial equipment such as CNC machinery to allow upgrading from older RS-232 serial controllers and robotics, since they can keep software compatibility. The device attaches to an RS-232 communications line and the ...
