IBM (VM) to UNIX communications

[Dave Buck]

For file transfer, I'd suggest a synchronous link to the IBM, and
either BSC or SNA batch-mode connections.  The standard rje mechanism
allows you to send and receive files readily (some shell scripts may
be required to customize for your intentions) to standard IBM
synchronous software.  As I understand it, to use an asynch connection,
there'd have to be a Series/1 frontending the IBM, so synch is probably
cheaper.  TCP/IP is probably the perfect solution, but needs to be
implemented on both ends.
Besides AT&T's rje communications package, there are other commercial
packages for BSC and SNA connections; my company is a supplier of such
products for many UNIX-based machines (there are others, obviously!).
PROFS is based on IBM's SNA Logical Unit 6.2; AT&T is rumored to be
finishing up an interface for LU 6.2 (details unknown to me).
My company has existing LU 6.2 software, but at the moment it interfaces
to IBM's DISOSS, a distant relative to PROFS (and of course, PROFS
interface will come from us some time in the future!).
