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
