Motherboard of the NeXTcube from 1990 having a Motorola 68040 (25 MHz) and a digital signal processor Motorola 56001 with 25 MHz which was directly accessible via an interface. In most designs the 56000 is dedicated to one single task, because digital signal processing using special hardware is mostly real-time and does not allow any interruption .
DCD is a signal sent from the modem to the computer. (Note that DCD also remains high if in command mode after a +++ escape sequence, but in practice, software uses this so rarely, if at all, so it's not really an issue.) The modem interprets the Data Terminal Ready (DTR) pin as a signal from the computer to know when it wants to terminate a ...
The result was the Network Test Automation Forum entity, which was set up in 2010 following the first face-to-face meeting in Montreal. [3] [4] [5] The NTAF (Network Testing Automation Framework) aims to streamline and enhance the interconnection of commercial testing tools and data communications infrastructure within the telecommunications ...
The virtual CD-ROM switching utility manages the switch of mode from disk to modem, the latter disconnects any mounted disk containing software we do not care about that will not work anyway and, crucially, creates a modem port/serial device (usually /dev/ttyUSB0) for the networkmanager.

Radio Service Software (RSS) is a software package used to program commercial Motorola two-way radios and cellular telephones. [1] An update of RSS is CPS, a Windows -based version of the package used for some of Motorola's newer radio models.
PowerQUICC is the name for several PowerPC- and Power ISA-based microcontrollers from Freescale Semiconductor.They are built around one or more PowerPC cores and the Communications Processor Module (QUICC Engine) which is a separate RISC core specialized in such tasks such as I/O, communications, ATM, security acceleration, networking and USB.
In 1976 Motorola switched the MC6800 family to a depletion-mode technology to improve the manufacturing yield and to operate at a faster speed. The Peripheral Interface Adapter had a slight change in the electrical characteristics of the I/O pins so the MC6820 became the MC6821. [1]
A null modem adapter. Null modem is a communication method to directly connect two DTEs (computer, terminal, printer, etc.) using an RS-232 serial cable.The name stems from the historical use of RS-232 cables to connect two teleprinter devices or two modems in order to communicate with one another; null modem communication refers to using a crossed-over RS-232 cable to connect the teleprinters ...
