We need to support TCP/IP on a 3090 running VM.  The two possibilities
we're looking at hard are:

1) an Ethernet interface, probably BusTech, and the FAL software.

2) a protocol converter, probably Mitek.

I've heard nothing but good about the BusTech unit, but would be interested
to hear from Mitek users.  Most particularly, Mitek claims that it is more
efficient to do a protocol conversion outside the mainframe and then have
their unit speak SNA to the mainframe.  This doesn't make any sense to me
because I would think that the mainframe would still have to implement SNA
to carry the traffic, and isn't that just as many cycles as implementing
TCP/IP?

Thanks in advance for any info.
