What is the best terminal emulator for the HP-48? Are there any written in machine language so they are fast? The RPL ones that I have seen so far have a display rate of a few characters per second at most. Thank you very much for your help Dr. Thomas Huber HUBER@GAC.EDU , HUBER@GACVAX1.BITNET Physics Dept Gustavus Adolphus College St. Peter, MN 56082

Well the best that I have found, came from hpbbs. Since, I can now get stuff from there via telnet, I have found a few nice things. I have several terminal emulators and like most people, have found that they are terribly slow. I know why. The reason is that most of them spend half their time trying to make sure they don't overflow the buffer and I know that TERM2.1 has commands just for killing the buffer. It will choke if it receives a line or two at 1200 baud. Guess what people.. Your hp48sx has automatic flow control. IF you edit your IOPAR such that the third and fourth values are not equal to 0 then you have Xon/Xoff. If the buffer fills up the hp will stop the host and if you can possibly fill the host's buffer then it will send an Xoff and stop the hp. Very slick. All this leads to a short (currently 1415 bytes) RPL terminal emulator that runs faster than any of the other ones.. It is extremely simple and has a few oddities, BUT it will NOT lose characters. It has been used at 9600 baud to log in and seems to work fine. The only thing that it won't do is linefeed. It wraps fine and scrolls fine but will not drop a line when it receives a linefeed. This was necessary to filter out all linefeeds as it was having probs with them. This is very easy to get used to. I have spent nearly 2 hours (non-consecutive) logged inot my account with the hp and this program. It is available at wuarchive.wustl.edu in systems/hp48sx/coms and is called dte48. IF anyone finds that they can add to this little beast and still keep it fast, I would love to see the mods.. ian -- -=Runaway Daemon=- P.S. I have also used it a bit with my friend's 48 and my 2 1/2 foot hp48 to hp48 cable. Cute way to talk.. No local echo, but I may fix that too, with an or gate or two. ;)

How about posting this neato program to usenet?
