[u3b.tech] IBM synchronous interface problems

friedl@mtndew.Tustin.CA.US (Steve Friedl) (08/07/90)

Hi folks,

     I am wallowing once again on this IBM 3270 interface.  My
customer has a 3B2 and wants to talk to the VisaNet Automated
Clearing House, and the PC we have to interface with has a 3270
coax card in it (IRMA, I think).  It is my understanding that
this coax expects to talk to a host computer.

     On the 3B2 side, we can get the ISC (Intelligent Serial
Controller) card with many various software options, but I
believe that ultimately the 3B2 looks like a 3278 (?) cluster
controller.  The ASCII terminals on the 3B2 will appear as 3270
terminals, and the synchronous side of things also expects to
talk to a host.  The sync interface is with a DB25 running what I
believe is RS-232.

     Black Box does not know the 3B2 at all, but they are
guessing that since both the IRMA card and the ISC card are
expecting to talk to a host and not a peripheral device, they can
do nothing more than stare at each other waiting for commands.
They tell me that they know of no black boxes that will connect
coax and RS-232.

     Is this understanding correct?  My customer has hardware
sitting idle until I can figure this out, and I am having the
growing feeling that I am S.O.L.


     Thanks to

        Andy Behrens @ Burlington Coat
	Todd Koeckeritz @ Euler Solutions
	Ken Lerman @ Stepstone
	Phil Hughes @ SSC

     for responding to my previous post on this.  I think there
was another response, but I think it got routed to /dev/null
by mistake :-(

     I hate bisync.

     Steve
