Serial port multiplexor

Make sure you have a backup kernel section to boot from if things get messed up. One thing to remember is that you have to switch pins 2 and 3 if you go from a real terminal to a PC, or use a null modem adapter. Serial Mux revisited. Since all control for this is done with four lines from the Basic Stamp. We simply built a keypad from a 74C , put 2. We then just mounted the keypad on top of the Wyse terminal, and it works just swell.

For some insane Z hacking and an opto-isolated parallel port interface, check out , my Z homebrew computer construction site. To put my homebrew to good use, I actually did port both this and the remote power control project to my homebrew computer.

Included: A server, which manages the serial port and shares it over TCP with any number of clients; a client, used to interact with the connected device either via text terminal or via script ; and a logger, which receives a copy of everything going through the serial port and timestamps it.

About Serial port multiplexer over TCP. Resources Readme. Each port is configurable in terms of baud rate, parity, number of bits and number of stop. On the host side the serial streams could be multiplexed through the use of a Windows driver or a special DLL program. Multiple slaves ATmega connect to master, via a parallel bus, to provide two serial ports each. Multiplexed commands sent to the master are routed to the appropriate slave. Likewise slave-received signals are routed back, through the master, to the PC in a multiplexed stream.

Gene Breniman, project designer, said that in addition to the slave serial port cards, other devices could be built and added to the stack to provide other services of interest to system integrators. This guide helps you to learn and understanding everything you need to know about the Raspberry Pi computer, its background, purpose, system specs, the software it runs and the amazing things it is capable of.
