i trying split physical serial port (com3) 2 or more virtual ports using com0com create virtual ports , hub4com split them.

here commands use create virtual ports:

install 0 portname=com100 portname=com101
change com100 emubr=yes, emuoverrun=yes
change com101 emubr=yes, emuoverrun=yes
install 1 portname=com110 portname=com111
change com110 emubr=yes, emuoverrun=yes
change com111 emubr=yes, emuoverrun=yes

the commands use split port:

hub4com --route=0:all --baud=115200 \\.\com3 --baud=115200 \\.\com101 --baud=115200 \\.\com111

here output along error get:

no route flow control
started com3(0) started com101(1) started com111(2)
