[Dx4win] Computer connection to FT-1000MP

[Jo, YC0LOW]

I apologise if this question already discussed here before. I  just joined the maillist.

I am running v6.03 and would like to do CW keying with it. All soldering for serial port (DB25) CW key interface have been done. But, there seemed no 'dah' exept 'dit' only.

Please advise me what setting (in the PREFERENCE) should be done. Or, what MENU in the MP should be changed?

Tnx es 73 de Jo, YC0LOW
