The ZMODEM Asynchronous Inter Application File Transfer Protocol Chuck Forsberg Omen Technology Inc Chuck Forsberg Omen Technology Inc 17505-V Northwest Sauvie Island Road Portland Oregon 97231 Voice: 503-621-3406 Modem (Telegodzilla): 503-621-3746 Speed 1200,300 Compuserve: 70715,131 UUCP: ...!tektronix!reed!omen!caf DSZ(1) XENIX System V (OMEN) DSZ(1) NAME dsz - YMODEM, ZMODEM file transfer subprogram SYNOPSIS dsz [port N] [speed S] [d] [restrict] command ------- DESCRIPTION Dsz uses the YMODEM or ZMODEM error correcting batch protocol to transfer files over a serial port with a variety of programs. Dsz is designed to be called from a communications program or bulletin board to perform file transfers. Dsz uses its own modem I/O. The original interrupt vector and UART interrupt configuration are restored on normal exit. Dsz expects its standard output to point to the console or a logging file, not a modem port. The available commands are: port N select port N (n = 1,2,3 or 4) Default is port 1 (COM1) or read from the DSZPORT dos environment variable. speed S Set specified speed, default is current speed. d Disables carrier dropout monitoring, for modems that do not properly drive the "Data Carrier Detect" input on the PC. LARG Convert ARG to lowercase, then parse arg. restrict Restrict pathnames to current disk and directory tree. sz [-Vabnpr+y] [PREFIX=p | ONAME=n] afn ... sb [-Vk] [PREFIX=p | ONAME=n] afn ... rz [-Vabnpr+y] rz [-Vabnpr+y] file1 file2 ...

NOTES Page 1 (printed 12/22/86) DSZ(1) XENIX System V (OMEN) DSZ(1) Dsz sets the UART shift register to 8 bits no parity; the original parity setting is lost.
