[WriteLog] G4ZLP interface CW/Rig control same port

[WK0F]

Hi,
I purchased a rig interface for 746Pro from G4ZLP.  It also has the 
provisions to key CW on the same serial port. It requires the RTS for 
TX.RX switching and DTR is used for direct cw keying.  Does anybody use 
this or a similar interface and is there a way to make it work with 
Writelog?  Here is a clip from my writelog.ini file....
[PORTS]
LPT1=0x3bc
CWPTTCONTROL=2
CWPTTDELAY=0
dvktype=3
dvkport=4
cwtype=2
cwport=6
dvkstoploop=1
dvkechomic=1
Comm1Used=USED,POLL,45
Comm1RigManager={D0DE9422-0517-11D4-9D1B-00105AA43DDF}
Comm1XmitControl=ALWAYS
Comm4RigManager={D0DE9422-0517-11D4-9D1B-00105AA43DDF}
Comm4XmitControl=ALWAYS
LPT2=0x378
LPT3=0x278

Thanks!
