95LX sending at 57600 baud, line history optimisations, third 95LX
2022-10-16
Today during the file transfer between the HP 95LX (running PD ZModem version 1.26) and the Linux box (running Debian's sz/rz) I tried out sending from the 95LX at 57600 baud. I used the command line zm -88 -c1 -b57600 -h -d sz *.com. It worked, although the resulting Bytes per second rate was below 2000 (up from less than 1000 for receiving with 9600 baud), so not as much of a speed up as one could hope. But I am happy that it works at all, and sending multiple files using a single command also works very well. I did notice that the labels within the PDZM window do not seem to be readable; there's a bunch of numbers but no visible labels that indicate what those numbers are. I seem to recall from using PDZM on the server and the DOS box that there are labels there, and the space is certainly enough to hold such labels.

95LX file transfer woes and backup battery tray
2022-09-28
Yesterday while setting up the file transfer between the HP 95LX and the Linux box I noticed that I'd bent one of the pins on the 95LX's serial connector. Luckily it was one of the outer pins, not the inner two which actually carry data. I returned it into the correct position with some difficulty, using tweezers.
Script for lDebug (SLD) file for the HP 95LX, and more lDebug development

Having adjusted the R, U, D, and E commands to be more 40-column friendly I am currently using the following script for lDebug (sld) file to set up the debugger:
r dco or= 800 r dco6 or= 1200 r dco2 or= 111 r ior = #16 r ioc = #40 r dao or= 80
95LX hang, PDZM, Zip, lDebug line history comments

The other day I managed to hang the 95LX again, to the point that Ctrl-Alt-Del did not work. This time I used Shift-Ctrl-On to reset the system. This reboots and queries whether to re-initialise the RAM disk. I chose "No". I found that while the disk contents and settings where preserved, the current date and time were not. (Supposedly this way of resetting may damage the RAM disk contents even if you reply not to reset the disk memory. So perhaps don't repeat the experiment.)
