Subject: [Elecraft] RS232 troubles
Hi there,
I have following problems with my RS232 K2 connection:
On a desktop PC with WIN7 everything working OK, all COM ports including
USB/COM adapter running without any issue. When I am reconnected same
USB/COM adapter with the same cable (between K2 and adapter) to the USB
port on laptop, no communication. Of course the driver in laptop is
installed and from the utilities and hardware control looks all OK. USB
ports on laptop are working (checked with USB flash). All parameters on
the COM port are the same as on desktop PC. I am on the end of my
knowledges now, any help?
Karel, OK2FD
