[bit.listserv.ibmtcp-l] virtual 3767 support

SNSTR@TTUVM1.BITNET (Steve Strickland) (02/09/90)

hi,
Users that connect via TCP, but dont use tn3270 must emulate a 3767(twx?)
device.

We were needing these 'line mode' users to dial vtam.

For full screen users we genned some local 3277 devices, and defined them
to VTAM with an LBUILD major node.

We guess that the dmkrio needs to be genned with a 270x type device.  But
what does VTAM need?  Has anyone on the list implemented line-mode-dial-vtam?

Thanks in advance
Steve Strickland

Before you can even worry about what VTAM would require, you have to get past
DMKDIA. DMKDIA does not allow SNA devices that are not of the graphic device
class (CLASGRAF) to dial. A line-mode TCPIP connection results in an RDEV
created by SNA CCS which is of the terminal device class (CLASTERM), device
type telegraph (TYPTELE2), which DMKDIA will not permit to dial
(DMKDIA743A DIAL function not available).
