I'll need to take a look at it. ... A quick look at https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.1.0/com.ibm.zos.v2r1.istimp0/append.htm shows that TSO still support non-3270 VTAM terminals. It might be interesting to write a "3767" emulator (hum, that may just be telnet) to have a UNIX session "logon" to a 3767 TSO session. Hum, I need to think about this a bit. Not that I'm likely to actually do anything. My interest in z/OS, and computing in general, is tending downward for various reasons. > > > -- > Shmuel (Seymour J.)
