Re: Connecting a Thinkpad to the AS/400

The only ThinkPad I've connected via Twinax was a model 760L (760EL ?).
Using CA/400 for Win 3.1 V3R1M1 and I had a problem because we have Twinax
baluns, hub & twisted pair wiring.  The setting of CheckAddr=No in the
PCSTDLC.DAT file fixed the problem with twisted pair.
(By the way, it has an IBM PCMCIA 5250 adapter.  IBM just came out with a
newer 5250 Express adapter but ovbiously haven't tried it yet).
Anyway, we upgraded this ThinkPad to Windows95 and CA/400 for Win95 V3R1M2
with the new 32bit Twinax support.   Could not get the ba***ard to work 
with the UTP wiring (have sent a few traces to IBM and they are currently 
looking at the problem) - BUT the connection does work flawlessly if you
have the real twinax cable (you know, the stuff that you can use to moor an
Oil Tanker with if necessary).  A salesman took the ThinkPad to IBM Jamaica
for a week of demos and had no problem with real twinax cabling.
Have also looked into the Affinity Systems Plug 'N Play 5250 adapter but
have not yet tested one.

(PS - we also couldn't get an Aptiva connected via either twinax or SDLC
adapters, but it worked OK with a PCI Ethernet card running both AnyNet
under Win 3.1 and TCP/IP under Win95.
