DIRect modem or Accoustic CouPlers. Radio Shuck lists Accoustic Couplers at 
about $100. Hey, gang, don't they come any cheaper?!

Or he who keeps repeating himself :-]. Do you really need pinouts? 
Operating the phone cord is quite simple. Plug into the Telephone
port, the brown wire goes to the wall, the silver wire goes to the
telephone. The wire is about 6 bucks. Set Stat M8N1E, 20, ORIG and
DIR. Call the number manually, hit Term when you get carrier.

Now to explain what all this means. The stat line looks like this.
Stat M8N1E, 20

"M" indicates the internal modem, which is 300 bps only. Other settings are 
speeds for data transfers, or external modeming, through the RS-232 cable.

"8N1" represents those standard comm settings which I won't explain now.
Mainframes are often 7E1, but just about everything is 8N1. If this is set
wrong, you'll connect and see writing, but the wrong characters.

Next is an E or D, which is Enable or Disable handshake. I don't really 
understand this one; perhaps someone can fill us in.

The number, 10 or 20, is the speed of the autodialer, which is rotary, and I
hardly ever use it. 

ANS/ORIG should be on ORIG, unless you're running a BBS or doing something
just as strange. 

The "Label" key toggles the visible function key explanations. I always
suppress them once I get connected, as they waste a line, but it's good to 
call them back to remind you how to download or something.

I'll post info about the cassette interface later when I'm sure I'll get it 
right. 

Now for some questions of my own:
The minibbs manual at the ftp site mentions a auto-answer curcuit. Does anyone
know how to make it? Also, what possible use could software to speed up the
internal modem to 450 bps be? Am I missing something?
