Mac OS X leopard, TERMINAL settings

How do I change the TERMINAL settings? There's no place in the menu. Can it be done
with UNIX in the TERMINAL program itself. I need to have the baud rate at 9600. data bits to 8, parity to none, and stop bits to 1. Surely this is possible on TERMINAL. Please help!

My VERY best thanks to Allen Eckert, Barney-15E, Baltmo, and Bob Harris, for responding to my original post on the Terminal query. Perhaps some brief clarity is in order: To operate a device which allows one to send and receive morse code on a short ware radio, it requires a USB Serial device cable (which I have) plugged into the MFJ CW Keyer/Reader where there is a LCD screen where the copy and letters appear. The TERMINAL setting must be as indicated in my original post. (baud 9600, data bits 8, parity none, and stop bits to 1. I can't figure out how to accomplish this in Terminal. I assume it can be done with UNIX. But I'm 80 years old and only did unix a little many years ago with eMail. Thanks again. I'm so grateful for the help from all of you. With every good wish!

I have reviewed the MFJ website and I am still not sure of a solution. I believe you want to connect your computer to this 'Keyer/Reader' using the serial port on the device. I have no idea what this is, some sort of short-wave Morse code thingy? (sorry I'm clueless.)

The Terminal program on your computer is a terminal emulator, but it is not capable of communicating with serial ports.

I don't know if zTerm will do what you are looking for, but it is a terminal emulator that can talk to serial ports. If you can get zTerm to recognize the serial port, you can configure it using the settings you need to match the device.

Sorry I can't be more help. It has been a while since I have used a serial port to communicate!

ZTerm is well established terminal emulator with serial port support.

You might also try CoolTerm <http://www.versiontracker.com/dyn/moreinfo/macosx/10915190>
"CoolTerm is a simple serial port terminal application (no terminal emulation) that is geared towards hobbyists and professionals with a need to exchange data with hardware connected to serial ports such as servo controllers, robotic kits, GPS receivers, microcontrollers, etc..."

Then there is QuickTerm
<http://www.versiontracker.com/dyn/moreinfo/macosx/28230>
"...QuickTerm is a basic ASCII terminal emulator. It can use any attached serial port, whether built-in or installed using an adapter such as a Keyspan USB-to-serial adapter. It allows full setting of serial port parameters, with or without handshaking. The name QuickTerm alludes to the fact that I developed it quickly, forsaking features I don't need to get a decent serial terminal emulator up and running..."

PortTerm
<http://www.versiontracker.com/dyn/moreinfo/macosx/19636>
"...Serial Port (RS232) reader/writer for Mac OS X with AppleScript and TCP/IP support..."

I just did a search at VersionTracker.com for "serial" and found the items related to serial port communications.

' I'm not too sure about the applications that BobHarris suggested as I myself have never used them - though they sound like they'll do what you need... I am, however, sure that what Andy suggested - ZTerm - will do EXACTLY what you need rpiercy, as it's the same program I myself use to connect via serial to the Unix servers I manage in my daily grind!

' Download ZTerm from the link / site that Andy has provided for you and install it to your system and start it up once you've attaached your serial-connection kit. The interface and options are pretty simple and easy to figure out.
' You should have no problems with it - the same exact setting you said you require are what I use almost daily in my interractions with Unix servers, so I know it works great!

' Let us know how it goes and if you need anything else!!!

AGAIN, my best thanks to all! I have installed zTerm per instructions from Andy Highberger & Menageryl. The settings are correctly placed and I get a dialog box with the name of the device, MFJ-464 at the top; ALSO, appearing are the words -- Direct Connect MFJ-464. Now, with embarrassment I must say, although with the cursor blinking nicely, I'm unable to generate and place copy text in said dialog box to send. What should I set next to accomplish this. Somehow I believe I'm VERY close.
Thanks so much, again.

The directions for connecting your device to the terminal program are located on page 28 of the manual located here:

http://www.mfjenterprises.com/man/pdf/MFJ-464.pdf

If you have the zTerm setting set as requested, do you get anything when you type on the keyboard? (do you have the flow control set to xon/xoff?)

Do you by chance happen to be using a Keyspan serial to USB converter? I use one of these to connect to the serial port on a Davis weather station and I believe I had to install a driver for the Keyspan device to work. It has been years since I set this up, but it may be that you need something like that to get the communication to work.

Aug 27, 2009 1:24 PM in response to Andy Highberger

First, the driver for the 9 pin connector from the USB to the device is installed, perhaps that's what's allowing for the words connected to appear of the MFJ-464 to appear in the zTerm dialog box. As suggested, I did install the Keyspan driver, but really nothing happened. The zTerm is still lit up indicating as you say, a partial connection. With the active cursor I still can't get keyboarded copy to appear. I sure appreciate the help out-here. Thanks again, Andy!

rpiercy,

I am at a loss. It is possible that the Keyspan serial device does not work with your keyer, but I don't see why it would not. With everything all connected up, have you tried restarting the Mac and seeing if it recognizes it then? Does your keyspan device have 2 ports like mine? If so do you get different results with the device connected to the other port?

Don't give up! Someone will figure this out!
