Hi I have a 3290 terminal that I'd like to put to some use. See email thread 'Talking to 3270 terminals?' that I started Jan 14. Somebody then pointed me to oec[1], which is an awesome project. I have built the hardware interface that is required to talk to a 3270 terminal on the hardware level. A picture of the interface and a video of the terminal can be found at [2].
Now, the friendly person who created oec says that the 3290 is a so called DFT (Distributed Function Terminal), in contrast to a CUT (Control Unit Terminal). Most 3270 terminals seem to be of the (simpler) CUT variant. oec only works with CUT terminals. Extending the functionality to enable it to work with DFT terminals isn't trivial. Does anybody on the list here know of additional documentation besides what's mentioned at [3] that could be helpful to implement DFT support? What would also be very helpful is a protocol trace of any kind of the communication between a 3174 and a DFT terminal. -Alex [1] https://github.com/lowobservable/oec [2] https://ahuemer.xx.vu/volatile/2020-05-11-P6C1Wc3u1wU/ [3] https://github.com/lowobservable/coax/blob/protocol/protocol/protocol.md ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
