As I said, it is fixed in V4.0. In V4.0 or with the patches, flow control is enabled by having ^S/^Q as the start and stop characters and having IXON set. If either is false, then the session is in passall mode. If ICANON, ISIG, ICRNL, IUCLC, IGNCR, INLCR are all clear then the port is in pasthru mode otherwise the session is in normal, interactive mode. BTW, if you use kermit, compile it in SystemV (make sys3) mode. Otherwise it will put the session into passall mode (it disables the stopc and startc characters) and you won't get reliable transfers. In System V mode, it will termio(4) which will interact with LAT properly. -- Matt Thomas Internet: thomas@decwrl.dec.com DECnet-ULTRIX Development UUCP: ...!decwrl!thomas Digital Equipment Corporation Disclaimer: This message reflects my own Littleton, MA warped views, etc.
