Connecting Amateur Radios and SWL Receivers to a Macintosh Serial or USB Port MacMemoriesManager Connecting your Ham Radio to a Mac Serial or USB Port. Note: These are not the only options, nor are they guaranteed to work with your particular configuration, they are just the devices that I have had good luck with here at Links to the manufacturers sites are included. If you have specific cabling solutions that have worked for you, please send them in by email and I will be glad to include them in future releases of the manual. Level Converters While some of the latest radios (ie Kenwood TS-2000) have an RS-232 port built into the radio, most radios require a TTL-RS-232 level converter. The manual for your radio will usually include a reference to which (if any) level converter is needed. The older Yaesu's use a FIF-232C while some of the newer ones like the FT-817 use a CT-62 cable/level shifter. The icoms use a CT-17.and the Kenwoods use an IF-232C.

These level shifters assume an RS-232 connection to the computer, so if you are using a classic Macintosh RS-422 modem port or a Keyspan twin serial adapter with RS-422 ports you will need a Mac Modem cable to convert the RS-422 levels to RS-232. If you want to home brew your own cable, see the section below on Macintosh Serial Port Hardware. The information here appears as a reference and a courtesy but Dog Park Software Ltd.

(Translation - please be carefull, I can not be held responsible if you let the smoke out of your radio interface or computer serial port). USB/Serial Converters microHAM has recently released combination USB/serial adapters and level converters: Cables and Adapters Macintosh Serial Port Hardware The DB-25 on the back of a Macintosh is NOT a serial port, it is a SCSI parallel port. Any attempt to use this connector as a serial port will NOT function correctly and may cause damage to the Macintosh and/or the equipment being connected. The two serial ports of a Macintosh are mini-Din-8 connectors which are labeled with a telephone (the 'modem port') and a printer ('printer port').

This is the pinout of the serial connectors. Macintosh to modem (or other DCE device) NO Hardware Handshake: DIN-8 MALE DB-25 MALE GROUND 4 O--+--------------------O 7 GROUND RECV DATA + 8 O--+ RECV DATA - 5 O-----------------------O 3 RD (Receive Data) XMIT DATA - 3 O-----------------------O 2 TD (Transmit Data) HANDSHAKE OUT 1 O--+ HANDSHAKE IN 2 O--+--------------------O 20 DTR (Data Terminal Ready) Note that in RS-232 the data signals are inverted (marking is minus) while the control signals are not (marking is plus). Thus the transmit data minus signal from the Mac is just right for driving the modem. Leave the transmit data plus signal disconnected. If you ground this you will short out a driver, and it will probably get hot. Similarly the receive data signal from the modem/DCE is inverted, so it can drive the Mac's receive data minus line, but in this case the receive data plus line is grounded to prevent any extraneous signals from being induced into the circuit. Note also that we are driving both HSKi and DTR from HSKo so the problems described above can happen.

Where did you get your usb-db9-rollover rj45 cable? So far all I have found are usb-db9 cables and then RJ45 adapters.
The camping mod is a fun addition to Minecraft that essentially gives you more ways to play the game. Using items like tents and multi-tools you can survive in the forest like a true camper. The mod also has multiplayer capability for camping with friends.
I suppose I could do one up myself, but I would rather drop a few bucks on one done right.;^) So, Terminal cannot talk out a port? I seem to remember that any *NIX terminal program could be aimed at any port, I just don't recall how. I figured the trick was how to point at the port in a way that says a USB port is a serial port. I have seen some stuff on the net saying you need a cable specific driver, but I can not confirm this.
