SyncTerm just emulates the speed (upon display of receive data), it stillãsends and receives at whatever the maximum through-put of the TCP/IP connectionãis.ãã > Same thing if I connect with an old Atari ST using a Lantronixã > telnet-to-serial device at 19.2.ããPoint-to-point serial connections have a fixed maximum throughout (DCE rate)ãwhile packet connections of inter-connected WANs (the Internet) do not.ãã digital manããSynchronet/BBS Terminology Definition #15:ãDOS = Disk Operating System (as in PC-DOS and MS-DOS)ãNorco, CA WX: 62.3øF, 73.0% humidity, 10 mph E wind, 0.00 inches rain/24hrsã---ã þ Synchronet þ Vertrauen þ Home of Synchronet þ [vert/cvs/bbs].synchro.netã
