Karl Denninger asked about doing ATTN on his tn3270 X-windows client. (I want a copy!) Basically, that's a matter of what the gateway expects to see and turn into an ATTN signal - it's not an in-band control sequence, but an out- of band signal sent from the 3274, or, in this case, the gateway, straight to VTAM as SNA control data. There is no AID generated; in fact, the application program doesn't see it as part of the datastream. Your best bet is to ask Mitek (!) and see what they want to generate an ATTN signal on the emulated SNA session. I looked at RFC1041, which is the only one to address tn3270 at all, and it's silent on the issue as well. -- Jay Maynard, EMT-P, K5ZC, PP-ASEL | Never ascribe to malice that which can jmaynard@thesis1.hsch.utexas.edu | adequately be explained by stupidity.
