[net.micro.cpm] Continuing Saga of the ADM3a/Kaypro Termcap

SECRIST%OAK.SAINET.MFENET@LLL-MFE.ARPA (04/30/85)

Dave Towson, et. al., thanks.  I am the originator of the ADM3a/Kaypro
termcap (or the one who POSTED it, anyway) that's been causing all of
the hoop-lah.

Perhaps the differences that were of consurn have something to do with
the fact that I provided an EMACS termcap entry, and this was being
compared and contrasted to a UNIX termcap.  I can state that I have used
this termcap on a Kaypro II with my own hands for hours on our VAX under
VAX/VMS running a Gosling EMACS.  As for the rest of the world, gee -
I dunno.  I hope it was of help, anyway.  And if you need the EMACS
termcap gobbledegook deciphered for you out there in netland, I will be
happy to provide the EMACS interpretation for you to the best of my
ability.  As to UNIX - go find a UNIX person, I'm a VAX/micro hacker.
Or a micro VAX-hacker.  Or perhaps - uh, never mind.  Best I not use
VAX, UNIX, and hacker in sentences lest I let myself in for a flame.

As to "tirades" and all of that, I am not upset - yet another flame in
netland, as I see it - and probably quite useful if you are trying to
get up on a UNIX system at that.

Some of you may have noticed differences in the padding number for
"cl", eg. :cl=3^Z:, cl=1^Z . I suspect that some of the problems
I have observed with the Kaypro 2x at higher port speeds (eg. 1200,
9600 baud) are related to needs for the microcomputer to do some work
each time it receives a new-line (linefeed) and/or return (CR)
character from a remote system.  Depending on the port speed and the
amount of cpu processing required by the communication program on
the Kaypro, it may be necessary to increase the padding on "cl"
(clear screen), and set or increase "dC" (number of milisec of
cr delay needed) and "dN" (number of milisec of nl delay needed).

Of course, adding padding and end of line delays to the termcap
may not be the whole solution.  Lack of data line flow control
(eg. XOFF/XON) can easily bring most communications programs to a
halt at higher speeds (by overflowing I/O buffers). In addition,
many communication and file transfer program assume a quick
response to transmission from the remote machine. That is, the
program will time out when the required response is delayed,
for example, by an overloaded time sharing system.
