Dream VFD

Any chance I could get something like this? 4064 VFD (or LCD with decent inversion. size is approximate) GRAPHIC (not alphanumeric) AT Keyboard GPO's if possible high speed (115Kbps) Serial, with standard MO controller functions Name the price. Is it possible? Is this a rediculous request? I know th...

Unable to use AT keyboard connection

Okay, so I soldered an AT keyboard header to the display. (5 data? points plus 2 ground? points) Plug the display in, then plug in a keyboard. Keyboards lights blink (NL, SL, CL) but do not stay on. Pressing the appropriate key does not make the light stay on. I started my comm port/lcd program and ...

Not exactly... Desolder (rather, DRILL!) an old AT adapter out of an old motherboard. Then, take a PS/2-AT adapter and fit it to my $30 17-key numeric keypad. The reasoning behind this - It's darn hard to have my VB app stay in focus to take keypresses! Anything going through the MO display will go ...

Sure enough.
7 solder points...
I did a quick search and it appears that no one sells those AT connectors any more. Time to recycle an old motherboard!

Thanks!

Found it -

Code: Select all

int d = 0xFE;
char d1 = Convert.ToChar(d);
this.axMSComm1.Output = d1 + "X";

Command Prefix in C#

How do I send a command prefix (and other control chars) in C#? (using the ancient MSCOMM control) In VB 6.0, this works - CP = Chr$(&HFE) MSComm.Output = CP & "X" I don't quite understand the theory behind what is being sent. The MSCOMM control accepts a text string in C#. Not sur...

LK404-AT(Rev 1.10) Keyboard Connection

How do I connect an AT keyboard to this display? I've looked on the back and there appears to be four sets of connectors - 9-pin Serial, 4-pin Power, 2-pin (GPO?), 2-pin ???. The manual says nothing about connecting the keyboard. Plenty about how to code to it, but nothing about connections... Any i...

www.toshiba.com Click support - computer systems - tech support center - pick your machine... Didn't see anything specifically for the serial ports, but you might try looking at the bios updates.

I suppose that the problem could be hardware related....
Rule it out by trying those same batch files on a newer computer.

Go to Tosh's website and see if they have updated drivers...

Okay, I apologize for being so abrupt before - it turned out to be more difficult than I thought! I'm running Win2k - different versions of Windows tend to handle classpaths differently, namely, Micro$oft has been more thorough at disabling classpaths in newer versions of Windows! When I registered ...

Ya, well no wonder it doesn't work.... Re-install java and the add-on. If your classpath is correct, javax.comm should automatically be imported when it sees the include statement. I don't have the java sdk on this machine, so I can't tell you off hand what the classpath should be. A re-install shou...

Piece of cake. javax.comm is an optional package for J2SE (Standard Edition) from sun. You need to download it... Do a search on their site for a list of various optional packages. Although, I think it's included in the Enterprise Edition, but don't quote me. Or, just click this link for the downloa...

Go to http://java.sun.com and do a search for "serial port". javax.comm.SerialPort is the package. Looks fairly straightforward. Let us know how it goes! http://www.planet-source-code.com is my favorite for code samples, but it seems fairly sparse in the java section... <font size=-1>[ Thi...

Holy ****!
Where did you get that case?! I checked with SGI about 8 years ago and they said empty cases could be had for +800. No power supply, even.
Where'dya get that from?!?!?
