For some reason, my previous upload of DTE48 lost some characters.
Let's try it again...
A few people have been asking for DTE48, a terminal emulator program
for the 48SX. Unless someone else out there has created a program
with the same name, here is what you have been asking for...
*********************************************************************
* DOCUMENTATION FILE FOR DTE48 V1.02 *
*********************************************************************
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 necesarily better
than any of the others.
Version 1.02 differs from previous versions in that incomming carriage
returns are replaced with an ASCII space before display. A more
generic SRCHREPL (search and replace) string function has been sustituted
for the previous FILTER function. Note that SRCHREPL requires MULTI
which is also provided. Incomming linefeed characters are stripped!
The main program, DTE48, can be modified so as to replace linefeeds with
a space or any other character.
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 five. DTE48 is the main executable. KEYMAP is a string
used for keycode translation. TOGF is a flag toggling function.
SRCHREPL strips or replaces characters in strings. MULTI performs an
operation till the results no longer change. Place the files in the
directory of your choice.

SRCHREPL 145.5 # FD08
KEYMAP 304.5 # 5BFC
TOGF 38.5 # 921E
MULTI 56.0 # 8FCF
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. Here is an example of the IOPAR list with XON/XOFF
enabled: { 4800 0 1 1 3 3 }
Characters will be displayed starting on the bottom line and lines
will scroll upwards as needed.

B b B ^B (ASCII 2)

DEL QUIT QUIT
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 and/or assembly
language versions. Use it at your own risk. Hack away at it and repost
only if you give me credit for the original version.

Make sure all carriage return characters (0d hex) are removed from
the ASCII string before you attempt to checksum it or convert it
using ASC-> .
Checksum for ASCII string (string on stack): D25F hex
Byte count: 2508.5
This is my third attempt at uploading this bugger. I am using procomm+
in ASCII upload mode via the 2400 baud HPBBS. I hope it works this time!akcs.kevin@hpcvbbs.UUCP (Kevin Jessup) (12/12/90)
OK! This time it uploaded fine because I just downloaded it and ASC-> converted it with no error. Hope it helps those of you that requested it. Kevin Jessup
