But HOW do I control the PA that also needs CAT commands to change bands.
Thank for your help, Herby, DB2HTA.

Serial Port Combiners
you will have to make sure the commands and protocols do not cause conflict between the devices, but this is a way for one RS-232 port to send data to other ports at the same time without using any other software on your PC.
Please read the info for these port sharing boxes so you know how and why the data from the devices are sent back to the PC and how the PC handles it all. It can be tricky and a bit of work.
oh - and these boxes can get pricey - The Black Box company makes them, but so do others.
Good Luck !
I use DDUTIL and my Flex to control an Expert Amp, SteppIR MonstIR, Rotor, LP100A and all my CAT enabled logging and digital programs.
DDUTIL is your friend..read the section on the Expert Amps. You need a Serial Port and a USB port to control your expert amp
If you do not have enough serial ports on your computer you can use USB ports or an combination of USB ports and USB Hubs.
Suggest you SEARCH this Community for Expert Amps.. we have written extensively how to do this
RS232, CIV, etc.. for CAT is the old fashion way... you have up to 8 receivers that can send "CAT" commands.... what we need is for manufactures of ham gear to get on the TCP/IP wagon.
It kind of sucks that I cannot control my Expert 1.3k remotely. I would love to send TCP/IP messages to it.
DDUtil offers a plethora of things for Flex users and once you start using it with AutoDrive, Macros, etc... you will not go back.
DDUtil connects to your Flex through TCP and Expert 1.3k to your PC through USB. You do not need to create a cable to connect Flex and Expert.... I find installing DDUtil easier than creating the cable to connect the amp and the radio.
Good luck... and do not get discouraged, it is a bit of a learning curve but worth the effort.
