Ken,

usb to serial adapters work just fine with hf remotes.
You can not define them as a serial port because they are not. They are a usb device first and foremost.

ioport=/dev/ttyUSB0                 ; Serial port for hf control (usb serial 1)

you must id the device number TTYUSBx

Some radios may require a rtc/cts jump on rs232 inputs and you need to be sure you are converting to correct level rs232 or ttl/-ttl.

another important point when you setup the line for your cat control for the ft-857/897 you will have to
use a real serial port. It will not work with a usb to serial adapter at all. I just set a remote base using an ic-706.

I had one radio setup that way using an old irlp board for logic for the ptt and cos. But do remember that when you computer
starts up you radio may go on to tx mode until asterisk reset's the port. if it does that will depend on which line you use for ptt.

look here at this website for more info about the parallel port setup. he has some nice circuit design's for this also.

George,

Yes that will work. You might also need to define the parallel port address in the node stanza for each node.
And if you think you might use a doug hall rbi-1, start using pins above pp3 (pin 4) then you will not have to redefine the pins when you do that.

Hey guys, before I start putting this together I have a question. I’m putting two nodes on one PC. One node is the usual repeater. The other is a FT897 type remote base. I really like using the parport for cos/keying. And I want to use the same PC’s port for both radios. As long as I keep the ppx=?? stuff within a particular radios node stanza will it work? Or if I have a ptt specified for one radio do I not have the ability to have another ppx=ppp under the “other node” even if (obviously) different pins for each. Like this:
 
 
 
[general]
 
[usb2428]
 
hdwtype=0
rxboost=0
txboost=1
carrierfrom=ppinvert
ctcssfrom=no
txmixa=voice
txmixb=no
invertptt=0
duplex=0
rxondelay=12
eeprom=0
pp10=cor
pp4=ptt
 
 
[usb28599]
 
hdwtype=0
rxboost=0
txboost=0
carrierfrom=ppinvert
ctcssfrom=no
txmixa=voice
txmixb=voico
invertptt=0
duplex=0
rxondelay=0
eeprom=0
pp2=ptt
pp11=cor
 
 
So before I go build this up I’m curious about this point. If it won’t fly I’ll add another PC for remote base controller. I have a few D945GCLF boards. I’d move the remote base to one using Limey
