[comp.sys.ibm.pc] Communication Programs

jbrennan@bonnie.ics.uci.edu (James Brennan) (02/01/89)

I was wondering if any out there knows of a good terminal emulator, preferably
public domain, for the Unix system.  I have an IBM compatible with a VGA
display board.  I would like to use the cards ability to display more than 25
lines on a screen but haven't found any such communication package.

Does anyone know of such a package, or even better have one.

Thanks,

Jim.

In general, the "Unix System" has a file called termcap or something like that
which contains many terminal definitions for all sorts of different bits of
hardware.  As long as a given terminal type, say VT-100 or Heath-19, is in
your TERMCAP file you could use any terminal emulator package which claims
to emulate the above.  Depending on the shell you use in Unix, there are
different ways of telling the system what type of terminal you are using.
Most commercial Comm programs such as Procomm or Qmodem have many different
types of emulation built in, but as far as I know these do not take advantage
of over 25 lines on any given screen, mainly because most full-screen
terminals only have 25 lines, thus more would be unnecessary and confusing
for full-screen UNIX programs such as EMACS.

	First you have to find a comm program that can produce more that 24 or
	25 lines in a screen. If you have Windows, the included comm program or
	a public domain program called proteus can do that.

	If you want to be able to use the extra lines effectively (ie in vi 
	emacs, etc) you have to change the existing entry (or create a new one)
	in your /etc/termcap file to the new line number.

d0|vt100|vt100-am|dec vt100:\
        :cr=^M:do=^J:nl=^J:bl=^G:co#80:li#24:cl=50\E[;H\E[2J:\
	....

	in the example above you need to change li#24 to 50 or whatevere your 
	communication program can produce. You can create a new entry in your
	termcap file that is the same as above exept for li# and call it
	vt100-xtra or something like that and you have to set your TERM envir
	variable (sh) to that value when you log in.

	I hope this helps..

    You might try hacking up the termcap entry of a aaa terminal.
    I used Telix's VT100 mode, switched the video to display
    50 lines in the misc options, then when I logged into xenix
    set a term type of 'aaa48db'. I could actually edit a file
    in 50line mode. There where some wierd scrolling at the bottom
    though.

Tell that last to someone who uses windowing systems like SunView or the
3B1 with a small font....

Telix 3.11 has 43 (EGA) and 50 (NOT 60) (VGA) line modes available on the
ALT-M menu.  Since my computer has a Hercules display card (as of a week
ago, to run Windows), I can't tell you how well they work.  They are both 80
columns; I've seen a VGA clone do 132x60, but have yet to see a terminal
program that uses it.

ZCOMM will read the number of lines and columns being displayed when it
starts up or regaind control after a shell escape.  This allows a wide
variety of screen "sizes" to be supported.

If the EGA/VGA video bios supports a function to switch to 132 columns,
ZCOMM can be set to use this call to switch between 80 and 132 colums
using the ANSI escape sequences.
