I use my HST modem with CTS/RTS flow control and DSZ's Zmodem protocol. Here are the settings I've found best for my application. Pay particular attention to &H1 and &R2, which are necessary for proper hardware flow control. Software flow control should not be used for file transfers in most applications where you are in direct phone contact with another HST modem (i.e., no packet switched networks inbetween). ati4 USRobotics Courier 9600 HST Settings....
