I use the VLT terminal emulator (available on Fred Fish disks). I had problems at first, getting the two machines to talk. I was convinced that the problems were related to the configuration of my calculator and VLT. I tried any number of combinations. The ACTUAL problem turned out to be what is noted in the "CAUTION" on page 632 of the hp48sx owners manual (Vol. II). The caution reads: -------------------------------------------------------------------------- CAUTION: When using the commands described below to transfer data to or from the HP 48 at 9600 baud, make sure the ticking clock is not in the display. If the clock is in the display, it may interrupt a transfer or corrupt the data being transferred. The clock display is described on page 439 in chapter 24, "Time, Alarms, and Date Arithmetic." -------------------------------------------------------------------------- Once I turned off the ticking clock, all went well (and has ever since). I upload and download stuff between my hp48sx and my Amiga all the time. Oh yeah, my hp48sx I/O settings are: IR/wire: wire ASCII/binary: ASCII (note: this works for most ml programs too, the calculator switches to binary if it needs too) baud: 9600 parity: none 0 checksum type: 3 translate code:1 My VLT settings (from my memory - cause I'm at work on my HP9000/370, which I also upload and download to all the time): Speed: 9600 Parity 8N0 (8 bits, no parity, 0 stop bits) Packet Size 96 (I think -- what ever it defaults too) I hope this info. helps you get it going. IT CAN BE DONE! Sometimes just knowing that helps. - Paul Vallis
