No, but this has been a favorite fantasy of mine for the last couple of years. We will be making improvements in this general area, however, that will benefit Linux. > Big discussion from one UNIXoid on the z/Linux forum on why > using the "normal" 3270 interface is unacceptable to a "real" UNIX > sysadmin (it's just too different and difficult to use - ascii async > appears to be the only acceptable answer to this person's desire).

And rightly so. :-) The I/O models for a character mode VT220 and a block mode 3270 are just too far apart to allow meaningful translation. It's been tried many times. (The ASCII terminal functions in the 3174 don't count.)
