Is your modem manufactured by Concord Data Systems, somewhere is Mass?
If so, I may be able to help.

CS> I have a friend who has a rainbow and we can't access the hard drive..
CS> We think that it might not be formated...we always get read erro

Does it have the standard 10MB hard disk?  And what version of MS-DOS are
you using?  Do you have a copy of DEC's Winchester Utility program?

It all depends on the application.  pins 2 and 3 are receive and transmit.
At a minimum they need switching.
If you do not want to tinker with breakout boxes or the insides of connectors,
you can go to your local computer store and explain your problem.  But do
not buy unless you can return it if it does not work.
Here is a bag of tricks that will allow you with trial and error to determine
the right connections for a null modem.  I have assumed that you are requestin
an Asynchronous null modem for 25 pin connections.  Synchronous null modems
have to exchange clock and are well defined.
If you have a breakout box it will help in setting up the actual
null modem.  The following steps should allow you to quickly determine
the proper configuration:
1) Pin 1 [Frame Ground] and pin 7 [signal ground] should be passed straight
through.  Pin 2 [Transmit Data] and Pin 3 [Rec Data] should be crossed.
2) Cross Pin 4 [Clear to Send] and Pin 5 [Request to send].  If the two comput
computers raise RTS when they wish to send and do not send until CTS is
high than this will enable full-duplex transmission.  If only one of the
computers uses this technique, then you may need to jumper 4-5 on each connect
but not pass them to the other end (this allows the machine to send as soon
as it is ready, without waiting for a CTS from the other side.
3)Connect the jumpered local pin 6 [Data set Ready] and pin 8 [Carrier Detect]
to the remote pin 20 [Data Terminal Ready].  Likewise connect local DTR
to the remote jumpered DSR and CD.

The breakout box allows an easy way to see what signals are present.  It
is also possible to use a volt meter to see what signals are present.
The minimum null modem connects 1-1, 2-3, 3-2, jumpers 4-5 on each side with
no remote connection, 7-7, and jumpers 6-8-20 on each side with no remote
connections.  The normal offical null modem connects
1-1, 2-3, 3-2, 4-5, 5-4, 6&8-20, 7-7, 20-6&8.

ps - in some modem applications pin 22 (Ring Indicate) is used.

pps - Several good books are: RS232 Simplified (Sorry I can not remember
the author and it is in the office) and KERMIT, A File Transfer Protocol
by Frank da Cruz Digital Press.

Frank
Just remember that the rainbows 96 tpi head is not wide enough to erase a
48 tpi track written by the IBM drive.  The resultant disk will appear readabl
on the Rainbow but will not be readable on the IBM.  I have always kept
a separate set of disks for transferring each direction.  This seems to
minimize the problems with reading on the IBM side.

I think that you already do this but only point it out so that the original
questioner will realize the "problem"

Nope, he called me voice almost a month ago to get my address so
he could send it. Can't figure out why he called though.  I did not expect
him to pay, and he has not. I guess if I am "abusive" enough Theall is gonna
send me the money. (Mayhaps he can even get his minions to contribute.) He
has taken over as "guardian of public morals" around here. After all, it's
a tough job, but somebody has got to do it.
What a shame that those poor people (all 6000 of them) around the world
have to read this reply on Usnet.

Nice to see you here after your long abscence. Even nicer to see
a breath of rationalism about the current furor. Especially nice to see a
customer who has retained his memory. Thanx for the kudos.

Bruce, the thread is dead, leave it that way.   If you had taked the time
to read ALL the messages, you would have noticed that  mr B. claimed that
everyone who posted, telling him to knock his BS off had ulterior motives
for doing it. this is not the sign of  a well individual.   he is just looking
for a fight,  I know of already 3 or 4 sysops that use KillrDog or varients
to kill all his  messages, because in all the time I've read the rainbow
echo, he has never posted useful information, just commercials.  " well,
you have this problem, and I can sell you this nifty manual that'll help
you fix it" or caca like that.  He has drived away users/  programmers like
Robert Catt with his unwanted attitude.
