[Elecraft] Serial port problems

[Gary Tuck]

For the first time I am having difficulties communicating with my K3/P3.  The only thing which has changed is an upgrade to the Mac OS.  Now running 10.14.5 Mohave.  I reinstalled the FTD driver for the serial cable, tried both my iMac and MacBook and neither finds the P3 responding. I have not been on the air for several months so I am not sure when the issue arose.

Has any had similar experiences and solved them?
