- Beginners guide to Comms on the Amiga
-
- By Perphirel
-
- Hello again, this issue I'll be looking into the strange world of comms
- and the Amiga, and how to get on the internet and bbs's etc. read on
-
- MODEM BASICS
-
- Well first of all you a need a thing called a 'modem'. This actaully
- stands for modulator/demodulator and actually coverts computer
- information/data into beeps and weird sounds and send them down your
- phone line to another computer.
-
- The speed of a modem is the most crucial thing in purchasing a modem, the
- faster you buy the less you pay in your phone bills.
-
- Modems range from 300 bps upto 33600bps or baud rate. Bps/Baud rate is
- how much data is sent through the modem down the phone, the higher the
- better. Dont buy anything under 14400 bps, unless you want a big phone
- bill. Currently 14400 modems are selling at about 60-120 pounds. A good
- make is USROBOTICS, and the Sportser modem is especially reliable, other
- good modems include, Zoom, Supra and Zxyel.
-
- BABT approved modems and none BABT approved whats the difference? Well
- BABT approved modem will work 99% of the time on British telephone
- systems. There has been trouble with some non-BABT modems, like not
- being able to hang up right. This happens when the modem has not been
- adjusted to the British tones. So if you buy a non BABT modem its your
- own fault if it don't work
-
- I'VE GOT THE MODEM NOW WHAT?
-
- Well you have to connect one end to your computer and the other end to
- your phone line. The Modem should be supplied with a cable that plugs
- into your Serial port of the Amiga, the other end is usually a telephone
- plug that plugs into your wall telephone socket. Firstly you need comms
- software, this should be supplied with your modem, If not you can order
- from your local PD library. A good PD comms software is called TERM.
-
- BASIC REQUIREMENTS
-
- Well you should idealy have a HardDrive and 1 meg of ram free for
- effcient modeming, but here is a list for the bare minimum for your
- machine.
-
- A500 1.3 : External Disk Drive HIGHLY recommended,
- 1 Meg Ram needed, more is recommended,
- HardDrive Recommended.
-
- Software: Ncomm3.0
- Internet: YES, no WWW
-
- Ok you can get Ncomm and a couple of other things on your disk by
- 'crunching' down the programs to fit on 1 disk, by using a utility like
- powerpacker.
-
- A500+ 2.0 : Same as above
- Software: Ncomm3.0 or any other
- Internet: Yes, no WWW
-
- Same as above but version 2.0 of the operating system gives more
- flexability and generally more stable.
-
- A1200 : External Disk Drive recommended
- HardDrive Recommended
- Extra 2meg ram + HardDrive required for WWW
- Software: Term, Ncomm + others
- Internet: Yes,Yes
-
- Version 3 OS now you can use WWW (world wide web) on internet and set
- your serial rate at 38400 to for more effciency.
-
- A4000/T : You got everything you need!
-
- Software: Term, Ncomm + Others
- Internet: Yes, Yes
-
- No problems here, you can use your machine with no problems, as you have
- everything you need already.
-
- SETTING YOUR SOFTWARE
-
- Basically all you have to do is set a couple of things:
- Only applies to 14400 modems and above
-
- 1. Baud rate set to 19200 for A500/+ owners or you'll
- get transfer problems
- 38400 + for AGA machines 1200/4000
-
- 2. Zmodem/Zmodem Upload/Zmodem Download/Zmodem Resume on
- This applies for all machines, note these functions
- can be found on your comms software options menu or
- something similar
-
- 3. RTS/CTS set this to on (all machines)
-
- 4. Parity, 8, Bits none, Stop Bits 1
- or 8n1 (all machines)
-
- 5. Duplex Full (all machines)
-
- 6. Emulation, set this to IBM usually
-
- 7. Intialization string, optional set to ATZ
-
- GETTING STARTED
-
- After you have done that try to dial a friends house by using the dial
- feature, the modem should dial out and your friend should pickup the
- fone, this is a good indication that your modem is working.
-
- Ok the next step calling a bbs, find a number (available in BBS section
- of miggybyte) and eventually your modem should make funny noises after
- being connected and you should get a string on the screen like this:
-
- CONNECT 14400/LAPM/V42/ARQ or somehting similar this means you have
- succesfully connected. Eventually you will get a prompt by the bbs
- Software and just follow the instructions and you should be ok.
-
- Sometimes your modem may not connect, if this happens consult your manual
- on commands, usually typing ATB1 or ATB0 does the trick, or try ATZ, to
- reset the modem back to normal.
-
- If you have any other problems you can try to contact the 'sysop' of the
- bbs you have called, by going to page option or call sysop on the bbs.
- They will usually help you out and be generally friendly.
-
- Anyway thats all for this time, I havent covered all the issues but just
- the basics, when you get online you should ideally call the sysop and ask
- for they will be glad to help you.
-
