*********************************************************************
* DOCUMENTATION FILE FOR DTE48 *
*********************************************************************
by Kevin Jessup.
DTE48 is a Dumb Terminal Emulator program for the HP48SX. "Dumb"
implies that the terminal cannot be read by a remote system or
respond to inquiry commands like a VT100.
AT least 3 other "terminal" programs have been posted for the 48SX.
All have various limitations. This one is not neccesarily better
than any of the others. [Yes, it is! IMHO, -jkh-]
FEATURES
--------------------------------------------------------------------
1.) Tramsmits upper and lower case as well as all of the ASCII
control characters.
2.) Characters are displayed AS THEY ARRIVE, not only when a full
line is available.
3.) The screen can be paused at any time. This assumes the trans-
mitting system handles XON/XOFF protocol and will not time-out
and start resending.
4.) 7 line by 22 character scrolling display.
LIMITATIONS
--------------------------------------------------------------------
1.) Probably not 100% reliable at 9600 baud.
2.) Control characters (ASCII 1 thru 26) are not processed and
are displayed as a dot. Checking each individual character
so as to process tabs, carriage returns and linefeeds slows
it down too much. An assembly language version is needed.
FILES
--------------------------------------------------------------------
There are only three. DTE48 is the executable. KEYMAP is a string
used for keycode translation. TOGF is a flag toggling function.
Place the files in the directory of your choice.
RUNNING IT
--------------------------------------------------------------------
Setup the 48SX I/O for the required baud rate and enable XON/XOFF
protocol. If you don't know what that means, read the manual!
Hit DTE48 to run.
Characters will be displayed starting on the bottom line and lines
will scroll upwards as needed.

Hitting the ALPHA key will pause the display. Hit it again to
continue. The left shift and right shift keys are active for
one keystroke only.
All keys not defined above generate a space.
DISCLAIMERS
------------------------------------------------------------------
NOTHING is guaranteed. I may or may not provide new versions.
Use it at your own risk. Hack away at it and repost only if
you give me credit for the original version. As always,
donations, government grants, presidential nominations, etc. are
gratefully accepted.
