M11 accesses (even in the Linuxversion) the hardware (i.e. the port device) directly. Specifying the port is the same under DOS and Linux. For example selects the 2nd serial channel (COM2 under DOS). Under Linux this normally corresponds to /dev/cua1 or /dev/ttyS1, although M11 is not aware of devices like /dev/cua oder /dev/ttS.

Go to ControlPanel->System->Hardware->Device Manager->Ports (COM & LPT). Here you find all ports in your system. If you are unsure about what port to use, you can try them all. (Remember to restart StokerKontrol between each attempt). From StokerKontrol v1.4 the program will find the port automatically without any configuration. See similar questions...

PC/104 systems treat serial ports as do ISA bus systems. All you need is a serial communication module that is compliant with the PC/104 bus architecture. There are usually no special steps involved in configuring the port, other than the standard port address/IRQ jumper settings often found on the module. Once the module is plugged in the stack, any communications software will be able to access the module in the same way it would be accessed if it were an ISA bus serial port.

There are two basic ways to do this. A simple but inefficient method is to set each port to the same IRQ and poll each port every time an interrupt is generated. Analogy - Imagine paging each of 8 employees offices to find out who paged you on the intercom. This is an example of polling. Each port/office gets checked but it takes time. The more efficient method is to have an Interrupt Status Port onboard the module. The interrupt status port tells you which port(s) generated the interrupt. See similar questions...

lines to your /etc/initab file: # this will initialize the modem port on startup md:b:once:i:/usr/sbin/runover .ttya /bin/stty 38400 You should of course change "38400" to whatever speed is appropriate for your site. See similar questions...

I use 3 com ports to run my navigation and communication software. One port takes the GPS nmea data, one port takes my Pactor Modem and one port controls the SSB. All sorts of peripheral equipment can be operated off of the USB ports. I keep an RF transceiver for a wheel mouse, a WIFI transceiver, an infrared dongle for internet over the cell phone and a printer plugged in all the time. See similar questions...

the FreeBSD kernel boots, it will probe for the serial ports in your system for which the kernel was configured. You can either watch your system closely for the messages it prints or run the command % dmesg | grep sio Here is some example output from the above command: sio0 at 0x3f8-0x3ff irq 4 on isa sio0: type 16550A sio1 at 0x2f8-0x2ff irq 3 on isa sio1: type 16550A This shows two serial ports. The first is on irq 4, is using port address 0x3f8, and has a 16550A-type UART chip. See similar questions...

You use ttydX for dial-ins. When opening /dev/ttydX in blocking mode, a process will wait for the corresponding cuaaX device to become inactive, and then wait for the carrier detect line to go active. When you open the cuaaX device, it makes sure the serial port is not already in use by the ttydX device. If the port is available, it ''steals'' it from the ttydX device. Also, the cuaaX device does not care about carrier detect. See similar questions...

You should be able to read from and write to the file handle using the standard I/O functions (read() and print()), but not the system functions (sysread() and syswrite()). It has been noted (but not tested) that modems that use the Hayes command set require a carriage return (\r) rather than a line feed (\n) at the end of the command. See similar questions...

COM 1 - 4 can be powered to either +5V or +12V. See page 37 of the manual or refer to schematic on back of Tek-465 under removable plastic cover. The system disk supplied with the Tek-465 contains a VFD test program. Browse the CD and look for the VFD program under the Test utility folder. See similar questions...

Check our Problems/Issues page for any special configuration settings that may be necessary for your vehicle. If all else fails, feel free to call or email us, making sure to provide the brand and model of vehicle, brand and model of PC, and version of VAG-COM. The diagnostic protocols require a degree of real-time response from the diagnostic tool. Certain other programs and services can prevent VAG-COM from responding in the timely fashion that the protocols require. See similar questions...

Serial communication remains the most popular choice in home automation. While many newer technologies are starting to use USB and ethernet interfaces, most security systems, infrared controllers, A/V devices, irrigation systems and HVAC systems continue to use serial ports. USB to serial converters may also be used for systems that require more than 4 serial ports. See similar questions...

You may add a multiport board to increase the number of serial ports, generally called COM port, on your system. See similar questions...

No. Quatech USB to serial adapters do not also included hubs. However, you can purchase third-party USB hubs to add additional USB ports to your system. The maximum data rate for USB 1.1 is 12 Mbps. USB 2.0 devices are capable of speeds up to 480 Mbps. Quatech USB 1.1 compatible serial adapters can reach speeds of 460.8 kbps--more than fast enough for most serial peripherals. Thus, there would be no advantage to implementing USB to serial adapters on the USB 2.0 standard. No. See similar questions...
