Info-Kermit Digest Mon, 13 Jan 1986 Volume 4 : Number 3 Departments: ANNOUNCEMENTS - Bitnet Files Updated MS-DOS KERMIT - H19 vs VT102 Emulation (many messages) Kermit under MS Windows MISCELLANY - Looking for Apple II CP/M Kermit Diskette XON/XOFF Deadlock between vt100 and Hayes Modem Bug fix for Prime Kermit server mode ---------------------------------------------------------------------- Date: Mon 13 Jan 86 11:22:40-EST From: Christine Gianone <SY.CHRISTINE@CU20B.COLUMBIA.EDU> Subject: Bitnet Files Updated The Bitnet Files have finally been updated. The Kermsrv File Server on CUVMA should now be able to supply Bitnet Users with up to date Kermit Files. JRD's MS-DOS Kermit is still an exception; it will be installed on Bitnet when it becomes the real MS-DOS Kermit. The way to get started with Kermsrv is to issue the following command to CMS: "SMSG RSCS MSG CUVMA KERMSRV HELP". If you haven't used Kermsrv for a while, you may notice that some recent improvements have been made. ------------------------------ Date: 9 Jan 86 00:24:09 EST From: John McNamee <jpm@BNL44.ARPA> Subject: H19 and VT10x emulation VT10x emulation would be nice, but not at the expense of H19. When you're talking to a host at 1200 baud the goal is to reduce the number of characters sent. VT10x is so verbose that operation at low speeds is painful. So go ahead and add VT10x emulation, but leave H19 for those of us still using dialup lines. ------------------------------ Date: Thu, 9 Jan 86 12:25:20 EST From: Ivan Auger <augeri%rpics.csnet@CSNET-RELAY.ARPA> Subject: VT102 vs H19 support... I never use kermit's H19 support, instead I use a VT102 emulator that allows me to run kermit without exiting the program. So, if H19 support is dropped, we won't suffer at all. (By the way, I also use emacs and haven't had any trouble with VT100 emulators except that it is a good program to find bugs in this emulators).

Just read the latest digest. Seems I came out sounding more vehement than I intended. Now that I've had a chance to put my brain in gear *first* (before my fingers take off), I can say what I meant to say in my previous msg: MS-Kermit would be much better off with the VT102's set of capabilities rather than the H-19's set. Uh, that means "conceptual set," as in, "Make the Kermit emulator do what DECL claims the VT102 can do *minus* all the implementation deficiencies in DEC's VT102, such as the XON/XOFF problem." I was unaware that the XON/XOFF business is a problem to some users, and now that I am aware of it, I have to agree that if the Kermit implementation of VT102 is going to include deficiencies such as that, then we're better off with H-19. There! Doesn't that sound nicer? -- Larry Afrin Dept. of Computer Science Clemson University ------------------------------ From: Roy Stehle <stehle@sri-tsc> Date: 10 Jan 1986 1519-PST (Friday) Subject: h19 support necessary I would like to request that h19 support remain in MS-Kermit. I am working on a VAX running 4.2 BSD UNIX. The text editor that I use (e) does not have a termcap for the VT-10X. There may be some time in the future that the editor will be enhanced to use the standard UNIX termcap, but I can't count on that. We have many h19 terminals in our company and rely heavily on their compatibility with existing software. ------------------------------ Date: Fri, 10 Jan 86 15:31:02 pst From: gould9!joel@nosc.ARPA (Joel West @ CACI) Subject: MS-Dos terminal emulation VT100 is fine. VT102 is better, and the standard for Terminal emulators. Junk the H-19. Any system that can handle it can handle the VT100, but not vice versa. If only a partial emulation is done, make sure it is an innocuous one. The MacKermit 0.8 is unreadable when switched to "bold"; fortunately, most systems don't use this. Also, for VMS users, a VT100-style keypad mapping would be real handy. I have a public domain Macintosh desk accessory (off the net) for those times I need one under VMS. Joel West CACI, Inc.

This is probably what we have on our Compaq 286, and it's no figment of our imagination. We used the straight IBM .exe (nothing to do with source) under MSDOS 3.x, and other than that, have no problems. ------------------------------ Date: Sun, 12 Jan 86 20:11:04 PST From: rag@uw-june.arpa (David Ragozin) Subject: H19 emulation in ms-dos kermit Although I can't speak for the comuputing center here at the University of Washington, I can say that our instructional computing system is heavily dependent on h19 and z-29 terminals. Most instructional computing uses a screen editor, which has been optimized for this h19 environment. As a result, the h19 emulation in kermit has been a very appealing aspect. Although I personally think the vt102 emulation would be quite nice to have, and it is desired by our Engineering College computing group, I would hope that some options could be maintained. The idea of having some generic terminal emulator modules, which could then hook into specific terminal emulator modules at compile time might be a way to go. As you also may recall, some of our staff created a very bare bones tektronics 4010 emulator which is invoked when heath mode is off, and the tektronics graphics code is received. I forwarded this code to you some time ago. Hopefully we will be able, without too much change, to repeat this graphics terminal extention with whatever new version you release. ------------------------------ Date: Thu, 9 Jan 86 16:45:32 PST From: walton%Deimos@Hamlet.Caltech.Edu Subject: Kermit under MS Windows Since Microsoft Windows claims to allow programs to run which are TopView aware, I thought I would try the version of MS-Kermit V2.28 jrd which supports TopView. I used the PIF file entries advised in PS:<KERMIT-MS>MSVIBM.TOP. The resultant program runs fine under Windows, except for the fact that the update to the screen after a CONNECT command is painfully slow--about equal to the speed of a 300 baud modem connection. Oddly enough, the program does not exhibit this behavior in local mode, after a DIR command to Kermit-MS for example. I have looked at the source code, but don't know enough about the TopView interface to understand how it works. Both the TopView and normal versions of MS-Kermit run equally quickly when run as standalone programs under normal DOS, so I would have no objection to the TopView version becoming the standard one. By the way, I built my Kermit from source using MASM Version 4.00. Using EXEPACK reduced the size of the executable file from 43,000 bytes to 32,000 (when the modules were linked in the order given in MSKERM.MAK).

Dyrenfurth) Subject: Looking for Apple II CP/M Kermit Diskette Although I have REALLY tried in this region, I have been unable to secure a working copy of Kermit-80 that runs on my Apple IIe (c/w PCPI CPM card, Videx Ultra-term 80/160 column card, Hayes 1200 smartmoden, Apple super serial card). I desperately need to get 1200 baud CPM communication up. Is there any way that I can buy a working disk from someone? I also need a version that works with a II+ (cw the ALS Smartterm 80 column card, the Micro-soft CPM card, and Apple Super serial card) ------------------------------ Date: 8 Jan 86 05:15:29 GMT From: Dennis Bednar <rlgvax!dennis@SEISMO.CSS.GOV> Subject: XON/XOFF Deadlock between vt100 and Hayes Modem Kermit XON/XOFF Deadlock Bug Caused by Hayes Command Echo Enabled I recently ran into a problem of kermit "locking" up sometimes when using a Hayes Smartmodem, and I thought I would share it with the net. Well, I looked into this problem and found that it was caused by me connecting to the Hayes modem directly, and and accidently typing control-s (XOFF). The ^S was passed through as data to the modem. At this time, I had set the Hayes dip switch to enable echoing during Hayes command mode, merely for convenience to me. This led to an XON/XOFF deadlock problem between the vt100 and the Hayes Smartmodem. Repeat by: # this is a comment # enter C-Kermit command mode set modem dir # kermit command to say direct hardwired line # I know, I know, C-kermit's dial command will interact # with the Hayes, and this problem will not occur if I # use the kermit "dial" command, but I was just experimenting. set esc 1 connect # kermit connects your terminal to the modem now # Now type AT several times, and verify that the OK prompt appears. # Now type control-s. # Now type AT, but you don't see OK. # In fact nothing you type is sent. This problem assumes that your # terminal understands that ^S inhibits the terminal kb's from # sending on the tty line. You MAY NOT BELIEVE THIS, BUT THE THE HAYES ALSO ECHOED the control-s!!!!!!! Therefore the ^S typed on my keyboard was passed through kermit, echoed by the modem, and passed back through kermit, and sent to my terminal screen. This caused my vt100 terminal's KBD LOCKED (Keyboard Locked) LED to turn on. If you try typing ^Q to break the problem, your terminal does not transmit it, because output is inhibited until ^Q is received from the host, which cannot happen, so you are deadlocked. Fortunately, since I was using a vt100 terminal, I merely pressed the SET-UP key twice, which turned off the KBD LOCKED light. For an ignorant user, this could be bad. Best solution: Disable Hayes echoing during command mode, and this problem cannot occur. Dennis Bednar Computer Consoles Inc.

Will get through the backlog of bug reports and such over the next week or so if the link stays going! Alan Date : 10 January 1986 From : Rick Burne, Ealing College of Higher Education, London UK Subject : Bug in Prime KERMIT in server mode In server mode PRIME KERMIT responds to an I packet with a NAK rather than anything sensible such as a qualified ACK or an error packet. This should be fixed in the next release from The Source, but in the meantime here is a quick edit to make it respond with an error packet.
