[RTTY] USB to Serial Port Adapter

[Scott Keating]

Not to complicate things but if you unplug those three adapters and plug
them into different USB ports do the COM-port addresses shift with them, or
do you have to use the same USB port each time?

Hi all,

I use 3 cheap (about 9 euro each) 'usb to comport' from Digitus/Prolific 
Technology Inc. for : Com4= PTT + FSK, Com5=TS-480, Com6=Packet.
(WinXP, Acer Notebook Celeron 2.6 with 4 USB, the last usb-port=mouse)

station again after moving home.  I was planning on switching from my tower
computer to my laptop computer as the station computer.  The laptop has only
USB ports while my 570D and Rigblaster have 9 pin serial ports. My first
thought was to go get two of the cheap USB to Serial Port adapters and use
them together to drive the Rigblaster and the 570D.  I'm told that you
cannot use more than one of the cheap USB to serial Port adapters at a time
and further more if you plug the cheap adapter into another USB port it will
assign a different COM Port number to the same adapter.  My next thought was
to look for something that allowed multiple ports and had static COM Port
numbers assigned to each COM Port connection.  I managed to find at least
two vendors:  CompUSB and Sealevel.  With prices ranging from $100 to $160
I'm just a bit skeptical.
