Request for WYSE60 termcapentry

Any one has a termcap entry for a WYSE 60 terminal?? My users are facing problems with colors settings and keyboarding mapping problem when they use the wy50 termcap entry. When one uses color with the wy50 termcap entry, the first character after changing the color always display. Thus, one has to insert a space for the string of character after setting/changing the color. Any help here?? Informix products uses CTRL-A to toggle between INSERT and OVERWRITE mode in its input field. This is not particularly intuitive to a first time user. Can the termcap entry be altered so that the user may pressed an insert key on the keyboard to change bewteen INSERT and OVERWRITE edit mode?? Thanks for any help. Do mail me direct, I can summarise and post the replies with two weeks. Calvin Ng.
