The adapter remains plugged always into the same USB port, for my adapter is COM4 I just disconnect the HP48 from the adapter only. I think it is probably a software problem, but once I reset the program, the adapter works perfectly.

I'll let you know if I nail this one. Anyone know if Conn4x will accept commanline parameters and the syntax?

Anyone >know if Conn4x will accept commanline parameters and the syntax? From the Conn4x help file under "Command Line": one parameter is allowed, the name of the communication port. Like HPx9G+, the USB port for the calculator. Other port names might be COM1, COM2 or whatever is shown in the Connect Using box of the HP 48, 49 Calculator Connectivity Kit main screen. -- - - - - - - - - - - - - - Bill Graves RKBA! bgraves(a)ix.netcom.com

Unfortunately there seem to be two kinds of pinouts in use for these serial port adapter cables. I found this out when hunting for one for my Asus P5Q Deluxe. I bought the wrong kind (of course) and then after some digging I found I had the right kind from an older Asus board all along, just sitting there in a box... |
