Does anyone understand how the sxt mechanisms work on Sys V.{2,3} ? I have the sxt(7) man entry which tells me something but not enough. I also have the shl(1) utility which works in it's own fashion but again doesn't give the game away. I understand how to open /dev/sxt/??0 and fire up the multiplexing with the ioctls specified in sxt(7). Whats really got me though is how the controlling process (ie shl) knows that I've thumped the ^Z key and should pop back into life. In time honoured tradition I've RTFM'd and grovelled through /usr/include/*.h to no avail. I cannot seem to find any answers. Any help/clues would be greatly appreciated. Many thanks.
