Good deal Doug, I'll keep this info on file.   I may tinker around  a 
bit over the next  week or so , since North American QSO Party RTTY is 
July 21-22.

My contest logger (Writelog) interfaces with MMTTY, but  it uses it's 
own screen  and has never seemed to read incoming text as well as MMTTY 
in a stand alone  configuration.

73 and tnx for the info, Steve KW3A
