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. -- Walt Haas haas@cs.utah.edu utah-cs!haas

We support TCP/IP on our IBM box and it works as expected. Emulation using FTP's TN3270 is amazing ( I rarely use berkeley tn3270 ). We use the IBM 8232 interface with an ethernet baseband interface ( I refuse to mention the manufaturer by name unless its in a bad light ) and it works as expected. I tried out the Mitek Box ( forget the exact model ) using a SNA connection. Amazingly it works very well, three of its neatest features over any of the other ethernet-3270 boxes are: an on screen help display it uses an extension of termcap so you can put in your own tty types it was capable of being channel attached. Mitek also has lots of neato software which I didn't try. cheers /S* latzko@rutgers.edu {backbone}!rutgers!latzko
