TIC won't lose data at all if you have the enhancement kit However, we've got an old (unenhanced) //e connected by direct line to our mainframe that runs Ted Medin's Kermit 3.xx at 4800 baud (emulating a VT-100) with NO LOSS OF CHARACTERS (Super Serial card driver; the mainframe supplies no nulls). There is some character loss at 9600 because Ted uses the 80 column card firmware and it's just not fast enough for 9600. My impression is that software that addresses the CTRC (is that the right combination of letters?) directly shouldn't lose characters (with interrupts enabled) at even 9600. I wish there was an interrupts by-pass in TIC for those of us who, for one reason or another, haven't interrupts available. LOTS of BBS's will supply (optional) pad characters which eliminate the character loss. Frankly, as mentioned frequently in the past couple of days, there are LOTS of Apple 2 comm programs that emulate a variety of terminals (even grungy old 1984 Apple Access // does a VT-100). I haven't seen a bbs where emulation was any advantage nor a mainframe on which Xmodem is of any use (I've heard of VAX's that support XModem for text file transfer only, but I've not tried one). It happens we have SOFTERM's transfer protocol running under VM on our IBM 3091, but the code was written locally and is not generally available (Softronics expressed little interest in it - we did ask). Hence, Kermit seems to be the way to go (most mainframes that support anything appear to support Kermit). The short version is that I find Apple commware that emulates terminals but doesn't support Kermit generally uninteresting. Software that only supports Xmodem can be very useful for communicating with BBS's but terminal emulation is superfluous on any bbs existant in this corner of the globe. --------------------- ARPA: sewall%uconnvm.bitnet@cunyvm.cuny.edu Murphy A.
