| 1. Any comm package will doue that supports XMODEM or KERMIT. Nearly
all BBS's use at least one of these fiel transfer protocols.
2. The DF224 settings should be fine as it comes from the factory.
The ONLY setting you should have to diddle with on the modem's
setup menu is PARITY. For example, if you are logging into a
system via Tymnet or TSN, you should set the PARITY of the modem
to EVEN (and your terminal software too). Otherwise, screen
prompts will appear as garbage characters. The default baud
rate from the factory of the DF224 is 2400. If you connect to
a system running 1200 baud, the DF224 automatically switches
to 1200 baud. All you need do in such circumstances is change
the terminal baud rate to 1200 after connecting.
3. Modem connect to the serial port. READ THE MANUAL for pin-outs.
If I recall correctly, the Amiga's have voltage on one pin that
can damage your modem is you connect it. Never use the full
RS232 line complement to connect from the serial port.

| 1356.2 | special cable required | AIKITS::WISNER | | Wed Apr 20 1988 13:22 | 25 |
| 1. Communications packages:
VT100.ARC or VT200.ARC in PAULY"AMIGA":: are great
programs, they have KERMIT and XMODEM built in.
REMEMBER: vt200 for use by DEC employees only.
To get this software you might ask someone in this conference
to mail it to you on a disk. Or go to a computer dealer with a
library of PD software and get a copy from a FISH disk or something.
(Contents of FISH disks are listed in this conference).
2. Default VT100/VT200 settings work for me.
3. Serial Port
4. MODIFIED RS232 cable. Do not plug in an ordinary RS232 cable,
it can do nasty things to your Amiga. See a previous note
in this conference for instructions on how to modify a RS232
cable for the Amiga.
try DIR/TITLE=MODEM
NOTE: Some dealers are not aware that a special cable is
required (like the guy who sold me mine!).

| Re: .0
If you have an Amiga 500 or 2000, you can simply drop by a store and
buy a "modem cable for an IBM computer." These cables will come with
the right sex and the minimum communications pins connected.

| 1356.5 | Cable sanity check | STAR::ROBINSON | | Fri Apr 22 1988 12:42 | 14 |
| Since it seems important to get the right cable, can I get a sanity
check here? Do I interpret these notes correctly to say:
Get a RS232-like cable that is designed to connect an IBM to a
modem, but not a "generic" RS232 cable? I asked one dealer about
the cost for an Amiga-to-modem cable and he pointed to a generic
cable. If the generic cable fits, but does "nasties" to the Amiga,
I suspect there must be quite a few nastified Amigas around.
Can I assume the cable that I connect from my home dec terminal
to the dec modem is wrong?
Thanks,
Dave

| 1356.6 | Don't use a DEC cable! | TLE::RMEYERS | Randy Meyers | Fri Apr 22 1988 17:56 | 9 |
| Re: .5
The generic cables usually have only the modem control cables wired
though. (I cannot remember off hand if that is nine or ten pins
wired through.)
Unfortunately, almost every DEC RS-232 cable I've seen has lots of
extra pins wired through. I strongly recommend against using a
DEC supplied cable.

| 1356.7 | NO problems with 25 pin straight thru | TEACH::BOB | Bob Juranek EKO/339-4312 | Fri Apr 22 1988 21:14 | 10 |
| I've used a 25 pin straight thru cable on several modems without
any ill effects to either the A1000 or the modem. The modems used:
Novation Smart Cat (ugh!), U.S. Robotics and even the Scholar.
The only problem I noted with the Scholar was an annoying whine
feeding thru to my audio circuits. This I attribute to the fact
that the Scholar can be used synchronously and the wine was the
modem clock feeding through the extra pins. This was fixed by using
the DEC cable. I've been using this configuration for 5 months
now with no ill effects.

| the problem is the CBM put power on some of those 25 pins. It
depends on if those "unused" pins are connected to anything
important in your modem. Expensive to find out you guessed wrong.
In the 500/2000, CBM current limited the power pins so that it
wouldn't fry things. Nice of them, but I still disconnected the
wires in my 25 pin cable (I use the same cable for the 2000 and
the 1000, they have different power pins but all are "unused" by
RS232).
