Few of today's computers have RS-232 ports and mine has no RS-232 ports but it does have three USB ports and are identified as Comm 12 and 13 when using a USB to RS-232 converter. However, neither of the two "Comm ports" are accepted by the configuration setup in Win-Test when using a K3 transceiver. Are there any solutions? W7UPF donsay2 at cox.net
