Just to keep life interesting, the MicroVAX 3100 has some "interesting" console ports behaviours based on the setting of the BREAK enable switch. When the console is not enabled to respond to BREAK, MMJ-1 is the console port. MMJ-3 will (confusingly) output the results of the selftest in parallel with MMJ-1. When the console is enabled to respond to BREAK, MMJ-3 becomes the console port, and MMJ-1 will (confusingly) output the results of selftest in parallel with MMJ-3.

For newer workstations (4-digit B/C/J class), PDC will revert to using SERIAL_1 if a USB keyboard is not detected at boot up. For some models of older workstations, you can either remove the framebuffer card, or hold down TOC for ten seconds while booting up. However, this does not work on all models.

A serial console is a device which allows command-line (like telnet/ssh) access to your server over a serial port. This allows you to access and fix your server if a network/firewall setting is remotely misconfigured. More importanly you can remotely boot into single user, change kernel image or options, and see all the messages sent to the console at boot. See similar questions...

Our EZ serial switch all have auto uplink function and all ports support it. So that means any port could be the uplink port to the other switch See similar questions...

Yes, because the SignaLink doesn't require a connection to the computer's serial port! Unlike other interfaces, the SignaLink never requires a serial port connection. This is particularly handy if your computer doesn't happen to have one! In addition to simplifying your installation, this feature also reduces the likelihood of the computer's RF noise getting into your radio. It also eliminates serial port related transmit problems that plague other interfaces. See similar questions...

The serial port should be located on the back of your computer. An example of a serial port image is provided here. See similar questions...

A#8.15: This is usually caused by serial port configuration problems. Common symptoms may be: % copycat .ttyco .ttya Error opening tty .ttya, aborting. or % /usr/sbin/getty 8bit.38400 .ttya getty: .ttya: I/O error The first thing to check is that the following GNO serial port drivers exist: /dev/modem /dev/printer Next, ensure the following two lines are in your /etc/tty.config file, and that they are uncommented: modem 2 .ttya printer 1 .

Yes. A closed "workgroup" environment can exist without having to uplink the EthIR Switch to an existing network. In this scenario several infrared devices connected to the EthIR Switch can share resources and communicate with each other, provide internet connectivity (if one device is connected to the Internet via a modem) and allow for printing services if a printer is attached to one of the other devices all in this closed "stand-alone" environment.

I've connected the USB to Serial adapter but it's on Com Port 5 (or higher) and your software only has Ports 1-4. This issue applies to the c\temp software only. This has been resolved with the new version of the MDAS-Pro software. If you do not have a copy of this software, please contact us. See similar questions...

Some unnamed clone cards have also been known to work, especially those that claim to be AST compatible. USB device support was added to FreeBSD 3.1. However, it is still in preliminary state and may not always work as of version 3.2. If you want to experiment with the USB keyboard support, follow the procedure described below. Add the following lines to your kernel configuration file, and rebuild the kernel. See similar questions...

It's system-dependent. Under Unix, you typically open, read, and write a device file in /dev, and use the facilities of the terminal driver to adjust its characteristics. (See also questions 19.1 and 19.2.) Under MS-DOS, you can use the predefined stream stdaux, or a special file like COM1, or some primitive BIOS interrupts, or (if you require decent performance) any number of interrupt-driven serial I/O packages.

It allows the application to interface to the GPS receiver through the same interface (commands and logs) as an external controller would through a physical com port. See similar questions...

The serial port is a 9-pin D shaped connector, similar to the video connector except with less pins. Usually, there are two on a PC. One may possibly be in use by the mouse (mainly on older machines). They are also referred to as Com ports or Communications ports. They are identified in Windows as Com1, Com2 etc. Look in the device manager under "ports" and you will see if you have any set up - if not, you may have to enable them in you motherboard's bios via the CMOS setup utility.

Answer: Three serial ports are provided. One can be used for external control from a modem or other serial device. The other ports can connect to managed serial devices (such as routers, PCs, servers, or other RS-232 devices). Port 3 is the default control port. Ports 1 & 2 use the PC standard DTE pinout, with RXD on pin 2, and TXD on pin 3 of the male DB-9. Port 3 has TXD on pin 2, and RXD on pin 3 of the female DB-9. Port 3 offers hardware handshaking; ports 1 & 2 do not . See similar questions...

No, but it is much more convenient. Most ham radio sound card software can control your PTT via a serial port. If your software doesn't have serial control, unlikely, or you don't have a serial port connected, you can use all of the RIGblasters with your radio's VOX. In that mode the sound card audio is fed to your radio and your radio's VOX circuit will activate transmit. See similar questions...

The 10-pin header next to the dip switches is a 2nd serial port. You can hook this up to your PC's serial port (with a null modem), and get connectivity that way, utilizing the 'qtalk' app on the i-opener. This seems to support zmodem, but the i-opener doesn't seem to have the sz/rz binaries. If it did (or if you can find/FTP them), it might make an easy way to transfer files to/from your PC.

First, make sure you do not have a keyboard and monitor plugged in. OBP will use the monitor for output by default if either are plugged in. You will need a null modem cable or a regular serial cable with a null modem adapter to be able to view output. Below is a list of commonly used programs for viewing a serial console. Check to see if your serial console application has the ability to send a break, as it can be very useful on a SPARC. See similar questions...

A. When attaching a PDA cradle to the serial (RS232) port, verify that the port assigned to your HotSync and/or ActiveSync software is Serial USB (COMx). The PA090 COM port assignment can be viewed by clicking START, SETTINGS, CONTROL PANEL, SYSTEM, clicking on the DEVICE MANAGER tab, clicking the "+" sign next to "Ports (COM & LPT) and looking for a "Serial on USB (COM#)" entry.
