[Elecraft] The no-serial port conundrum

[Joe Subich, W4TV]

Garry, 

Windows assigns the "Com number" to most USB converters when they 
are initially installed.  Windows will not reassign a com number 
once it has been used so if you move a USB converter from one USB 
port to another it will often get a new COM number (particularly 
in vista Windows 7). 

For quite a while FTDI based serial converters have been the most
reliable for amateur purposes due to driver timing issues with VB6 
and other compilers of that era.  Now Prolific have supposedly fixed 
their driver issues but I'm skeptical until we see more reports. 

73,
