Xref: Patch, See MS-DOS Kermit
Here is a new patch file for MS-DOS Kermit 3.11, dated 5 Nov 91. The new
patches are:
Patch #6 solves the problem of using 8-bit CSI vs 7-bit ESC [ in the
host command to end transparent printing, reported by Leslie Foster, and it
cures a bug in reporting the status of devices such as the printer and cursor
position.
Patch #7 solves a problem that prevented file transfer from working on SET
PORT TCP/IP connections when parity was set to even or mark.
[Ed. - Thanks, Joe! Readers, see below for Leslie Foster's message. The new
patch file is in kermit/a/mskermit.pch on watsun and is available as
MSKERMIT.PCH from KERMSRV at CUVMA on BITNET/EARN.]

This weekend I discovered that letting the QEMM v6 Stealth (ST:M)
optimization map away my VGA board's BIOS I also removed access to the same
by MS-DOS Kermit. Kermit looks for a signature of a video board's Bios when
asked to change from 80 to 132 column mode, and the common signatures are
text strings in the Bios. Alas, Stealth swiped the BIOS so no text strings
were visible. Int 10h calls work fine, as expected, but that's not what
Kermit needs in this case. So, before sending in a "broken" message on
Kermit let the video BIOS be visible and see if 132 column mode reappears.

Subject: MS-DOS Kermit 3.11 Printing Problem
Keywords: Printers, MS-DOS Kermit and Printers
We recently installed a copy of Kermit 3.11 to emulate a VT220 terminal in a
GEAC library system. We have been using version 3.01, but looked forward to
version 3.11 so we could display diacritics better. However, we are now
having a problem printing from the host to the printer attached to the PC,
that we did not have in version 3.01. In both cases, the options used are:
Display: Regular, 8-bit
Parity none
We have also installed a print spooler on the PC (20k). When files are
sent for printing in version 3.01, the "PRN" flashes on the status line
until the file is collected in the spooler, and when finished, the terminal
returns to normal, and the printing is done correctly.
In version 3.11, this does not happen -- the PRN in the status line stays
on, and the terminal must be reset with ALT=. In the debug mode, we can
see the characters required for printing being sent (ESC [ 5 i at the
beginning and ESC [ 4 i at the end). These appear in the SET DEBUG SESSION
display as follows:
~^[5iTEST^M^J^L^@~^[4i
(with TEST being the line printed.) It seems as if 3.11 is not interpreting
the 8 bit control characters for printing, while 3.01 could handle it. Also,
after receiving the 8-bit "stop printing" control sequence, the terminal
emulator begins to behave strangely, displaying control characters as
graphics.

Subject: Double Echoing Problem with MS-DOS Kermit 3.11
Keywords: MS-DOS Kermit 3.11
I have just installed MS-KERMIT 3.11, and I have noticed the following problem.
1. I start kermit, use the 'vms' macro that was provided in the kermit
distribution, set my port to tcp/ip, set the other tcp/ip parameters,
and connect to our VAX 9000. I get the username prompt, log in, and
everything seems to work just fine.
2. After a while, I get tired of the reverse video stripe on the
bottom of my screen, so I push Crl-], then M to toggle the mode line
off. The mode line goes away, but now everything I type is doubled
on the screen. Ie- typing 'dir' produces 'ddiirr'.
3. I push Alt-X, then show communications, and see that I am still set
at Duplex: full. My display setting is VT320, Regular, 8-bit, with
terminal controls set to 7-bit.
4. I reconnect to my VAX session with the 'CONNECT' command, and now
everything is back to normal. I can toggle the mode line off, and on, and
off, but still my display is as it should be. The problem does not seem
to re-appear until I log off, exit kermit, and then start it up again.
5. I am running a PC with DOS 3.3, using the packet driver for the 3c503
card. I also load IPX, and this copy of Kermit is coming off of a 3.10
Novell file server. I have tried to duplicate this problem while
communicating to the VAX with TES, but it does not seem to appear then.
I would be happy to receive any solutions to this small, but vexing,
problem. I have tried to give the critical information about my set-up,
if more information is helpful please let me know.

Keywords: MS-DOS Kermit 3.11 and TCP/IP
QUESTION: "How can I use MS-DOS Kermit's TCP/IP support and a Novell Network
at the same time?"
ANSWER: MS-DOS Kermit's TCP/IP support works only in conjunction with a
packet driver (see Joe Doupnik's article "Kermit, TCP/IP, Packet Drivers,
and the Future" in Info-Kermit V14 #5). To use Kermit, or any other TCP/IP
application, and your Novell services at the same -- for example, to be able
to transfer a file between your Novell file server disk and an IP host
computer -- your Novell network must be configured to use a packet driver.
Novell does not provide instructions for how to do this, so it won't do any
good to look in your Novell manuals. One commonly used method is provided
by a package of Novell shell drivers from Brigham Young University (BYU) in
Utah, USA. These drivers can be obtained via anonymous FTP (password guest)
from dcsprod.byu.edu (128.187.7.3). Use binary mode. The drivers are found
in the novell subdirectory in a self-extracting archive file called
novell.exe; they support NetWare versions 2.1 and higher. Transfer this
file (again in binary mode) to your PC and run it. This will extract the
component files, including a READ.ME file that gives instructions for
configuring your Novell IPX driver to use a packet driver.
For convenience, the novell.exe file is also available via anonymous ftp
from watsun.cc.columbia.edu as packet-drivers/novell.exe (binary mode).

Subject: Using BOOTP with MS-DOS Kermit 3.11
Keywords: BOOTP, MS-DOS Kermit 3.11 and BOOTP, Novell Networks
We are looking at making BOOTP service available for our academic users. I
see that managing IP numbers could be a problem but that Kermit can use BOOTP
to set IP numbers. We'd like to "idiot-proof" this as much as is possible.
Questions...
Where can I obtain BOOTP, its documentation, etc?
[Ed. - The BOOTP protocol is detailed in RFCs 951 and 1048. A UNIX version
of BOOTP is available via anonymous ftp (binary mode), from Carnegie-Mellon
University, LANCASTER.ANDREW.CMU.EDU [128.2.13.21], pub/bootp.2.0.tar. A
VAX/VMS version comes with TGV MultiNet 3.0. Reportedly, a BOOTP server is
available for DOS, but we have not located it yet. Anyone? In a pinch, it
should be possible to adapt the CMU BOOTP server for DOS via minor (?) edits
and then link it with the Waterloo TCP (WATTCP) kernel. And for Novell
networks whose only link to the IP world is through the Novell server, Novell
is preparing to release (at least in beta-test form) a BOOTP-forwarder NLM
for NetWare 3.11 servers, BOOTPFWD.NLM). Watch CompuServe NetWire or your
favorite Novell newsgroup or mailing list for further information.]
Can BOOTP restrict access in some fashion?
[Ed. - Yes, by hardware address. The BOOTP server sees the requestor's
hardware address in the BOOTP request packet and uses this to find the
associated IP address and send it back to the requestor.]
What happens if two systems have the same IP address?
[Ed. - The same thing that happens to your mail if your house has the same
street address as another house down the block. You have to control IP
numbers centrally. The BOOTP database is a good way to do this.]
How do others handle IP numbers when users can set their own in MSKERMIT.INI?
[Ed. - Administratively. The network manager hands out IP numbers, and has
to trust users to use them properly. Of course, this never works. User A
gives User B her Kermit diskette, complete with MSKERMIT.INI file containing
a SET TCP/IP ADDRESS command, and then as soon as both of them try to use
Kermit TCP/IP connections at the same time, only one of them works. The same
thing can happen with NCSA Telnet or any other DOS-based TCP/IP software.
That's why BOOTP service is a better approach for PCs: One network
configuration fits all.]
[Ed. - P.S. We still don't know for sure whether BOOTP service can be made
to work through a gateway. Has anyone out there got this to work?]

Keywords: Packet Drivers, 3Com 3C503, MS-DOS Kermit 3.11 and Packet Drivers
Hint for 3Com 3C503 users: When installing the packet driver for 3Com 3C503
cards, one has to pay attention that the memory on the card is *not*
disabled. It was in my case, and the 3C503 packet-driver would not complain.
Since DEC PATHWORKS (and probably other networks) do not require the memory
enabled on the card, the default is disabled. Maybe this fact should be
included in your BUGS&BEWARE file.
[Ed. - Thanks for the report. As you suggest, a note about this has been
added to the "beware" file, kermit/a/mskerm.bwr on watsun, MSKERM.BWR on
KERMSRV.]

Subject: MS-DOS Kermit on COM1 and COM2 in Windows
Keywords: MS-DOS Kermit and Windows 3.0, Windows 3.0
I am trying to get two copies of MS-DOS Kermit 3.11 running under Windows.
I have an early version of Windows 3.0 so perhaps it has problems.
However, I've created two copies of the KERMIT.PIF file, one called NCR.PIF
and the other MOTOROLA.PIF. I have two COM ports on my 386DX and a serial
cable to each system.
When the NCR.PIF file runs it goes to C:\KERMIT2 and runs MS-DOS Kermit 3.11
with 'set port 2'. When I do a "show comm" it tells me that I'm using COM2
with address \x2F8, IRQ3. MOTOROLA.PIF has 'set port 1' and reports COM1 in
use with address \x3F8, IRQ4.
When I start NCR.PIF and then start MOTOROLA.PIF, Windows says both
applications want to access COM1 - sometimes MOTOROLA.PIF does find COM1 and
tries to use the BIOS.
Have you heard of this problem before? I'm using DOS 4.01 so perhaps there
is a problem here too?
[From jrd - To make sure that COM1's IRQ 4 is not touched when starting COM2
(part of the "find the IRQ" test) specify the COM2 port parameters
explicitly as SET COM2 \x2f8 3 (port then IRQ). This will make Kermit
bypass the test and leave COM1 material alone. The problem here is how
people refer to COM2 as such: the second of two ports (that's what the BIOS
does) or the \x2f8 address (what most people do) or even what used to be
COM2 before they removed the COM1 device (happens often enough).]

P.S. I do have the WP30.INI file which is how I first discovered MS-DOS Kermit.
Did you know that WordPerfect Corp ships this file with WordPerfect 5.0 for
UNIX - that's how good they think it is.

From: Jeffrey E Altman <JALTMAN@CCMAIL.SUNYSB.EDU>
Subject: MS-DOS Kermit vs Windows vs 9600 bps and Above
Keywords: MS-DOS Kermit and Windows 3.0, Windows 3.0
The real problem with running above 9600 is that Windows 3.0 provides DOS
Applications with virtual services only. In other words, Windows is
capturing the Serial I/O data and then sending it to MS-DOS Kermit when
MS-DOS Kermit is next run. However, on slower machines (386sx on down) with
a 8250 or 16450 UART, Windows is unable to keep up with all of the Serial
Interrupts at 9600 or above. (The actual speed that may be used is affected
by the PIF settings, SYSTEM.INI settings, and number of applications
running.)
In order to resolve this problem you need two things. First, a 16550A UART
which supports a 16 byte FIFO buffer on the chip. The FIFO cuts the number of
Serial Interrupts down to one every 16 bytes (during continuous high speed
transmissions) instead of one every byte received. The second thing is a
replacement communications driver for Windows that supports the 16550A FIFO.
(It is rumored that Windows 3.1 will contain 16550A FIFO support.)
A company based in California called Bio Engineering Research Labs makes a
product called TurboComm which is a replacement Windows communication driver.
This allows much higher speed communication. It also provides true access to
Com3 and Com4 while under windows.
Unfortunately, I do not remember the phone number or address of Bio Engineering
Research Labs. I will try to forward it. The author does read the
WINADV/Communications forum on Compuserve.
The other method is to purchase a Hayes ESP board which provides instead of a
16byte FIFO buffer, a 1K byte FIFO buffer. It comes with drivers for Windows
3.0 and OS/2 1.x.

[From jrd - Jeffrey seems to be on target regarding the way Windows 3.0
handles the serial port. A 16550A UART chip can help if the software
requests it. MS-DOS Kermit exploits the chip (FIFO buffer highwater set to
8 characters to allow more arrivals while servicing) but it needs contact
with the real hardware to do so. A disappointing factor in today's market
of cheaper and cheaper boards is finding a serial board with a socketed
UART. Most of the serial port boards have UARTs implemented on some kind of
VLSI chip of unknown parentage. So I think we are stuck with what we can
get and hope that Microsoft can improve their serial port interrupt routine
code. Personally I've given up hope of "speed" when using Windows (even on
my 386 machine). It's nice to know that there are alternatives, so thanks
Jeffrey.]
[Ed. - In response to the many people who were wondering how Gene (E.W.)
Carson managed to run Kermit in a Window at 19200 bps on a PS/2-55SX, as
reported in Info-Kermit V14 #3... It turns out that Kermit wasn't actually
running at 19200 after all. Although Gene's MSKERMIT.INI file set Kermit's
port speed to 19200 bps, and Kermit displayed it as 19200, the underlying
Windows setting for the port was 9600 bps and, as Jeffrey points out, the
Windows setting takes precedence; Kermit was only seeing the "virtual port".
After making this discovery, E.W. reports that he changed the port speed in
Windows to 19200 and saw the same communication problems as everyone else.]
