ocr: As I indicated earlier, it is best to call DSZ from a batch file. I have included some samples below. Sample download batch file echo off DSZ port 2 speed 2400 r -y c:/download This file tells DSZ to use comm port 2, to operate at a speed of 2400 baud, to use zmodem as a protocol, to overwrite an existing file of the same name, and to use cindounload as a directory. (note: the / in the command is not a typo. It needs to be entered in that way.)
