[Dx4win] CAT and RTTY

[F6EXV]

Hi all !
I just plugged a CAT cable to my computer, and it seems to work fine, 
except that I operate my FT1000MP Mk V in RTTY using the packet connections.
The QSO is really RTTY but it shows PKT (which is a correct reading, but 
wrong info !).
Is this solved on the Yaesu, or through DX4Win ?
I use version 7.01, and Windows2000 XP.
Thanks in advance for enlightning me !
