    i am using the dos usd module from http://chipdos.com

    i used the uart connection of this module to pic as shown in http://chipdos.com/library/CD17Bxx-0v8.pdf

    i tie cts to ground and leave rts hanging.

    my problem is, the module doesn't seem to respond.

    i also need help in writing the program.
    i will be using ccs compiler.

    thanks...
