REPLY TO 05/02/90 23:28 FROM MAYBE@IGLOO.UUCP: Re: HP48 serial voltages
(Question)

 + The low voltage of the HP seems to be the reason that it simply won't
 + communicate with my computer.  I have a Toshiba 1200HB Laptop, and perhaps
 + to save battery power or money the serial port is not as sensitive as
 + it should be.  The calculator recieves text Xmited but somewhat garbled.{u!
 + The Computer recieves nothing.  What can I do?
 + How can I tell Toshiba that my serial port works with my modem, mouse,
 + but not HP48sx and therefore I want them to do something about it?
I'm not sure I'd blame Toshiba: when I got the serial interface kit
for my HP48sx,  I decided to use my Toshiba 1200HB to avoid crawling
around behind furniture with cables to connect to my desktop, and it's
worked fine.  I haven't tried moving files from the HP to the Toshiba,
but Toshiba to the HP has worked flawlessly, and I assume that there
is enough handshaking etc so that if the Toshiba totally ignored the HP
I'd know about it.
