_______________________________________________________________________________ PROGRAM: DSZ.EXE Version 05/29/87 PURPOSE: Utility to Transfer Files to/from Remote USAGE: Ctrl-Break to Abort DSZ [port n] [speed s] [z p_#] [restrict] command [-options] [filename(s)] _______________________________________________________________________________ note: Use MODE COM1:12,N,8,1,- in AUTOEXEC.BAT to initialize Port. DSZ reads the DOS environment variable DSZPORT=n to open COMn: DSZ sets ERRORLEVEL 0 if transfer successful (and 1 if not). _______________________________________________________________________________ Receive File(s) from Remote Protocol: DSZ rx -y Filename.ext Xmodem/Sum Ymodem/Sum DSZ rc -y Filename.ext Xmodem/CRC Ymodem/CRC DSZ rc -gy Filename.ext Ymodem-G DSZ rb -y Ymodem-Batch DSZ rb -gy Ymodem-G Batch DSZ rz -y Zmodem-Batch _______________________________________________________________________________ Transmit File(s) to Remote Protocol: DSZ sx Filename.ext Xmodem/CRC Xmodem/Sum DSZ sx -k Filename.ext Ymodem/CRC Ymodem/Sum DSZ sx -k Filename.ext Ymodem-G DSZ sb -k Filename(s) Ymodem-Batch DSZ sb -k Filename(s) Ymodem-G Batch DSZ sz Filename(s) Zmodem-Batch _______________________________________________________________________________ note: Xmodem uses 128-Byte Packets and CRC-16 error checking. Ymodem uses 1024-Byte Packets and CRC-16 error checking. Use SET 1:0,4:2,5:0,7:8,12:0 to configure TeleNet for Ymodem. note: Zmodem uses free-flowing Packets and CRC-32 error checking. XON/XOFF - Handshaking required for Zmodem-Batch Transfers. Use SET 1:0,4:2,5:1,7:8,12:1 to configure TeleNet for Zmodem. note: Ymodem-G uses free-flowing Packets and no error checking. RTS/CTS - Handshaking required for Ymodem-G Transfers. Use Microcom Network Protocol "MNP" Modems for Ymodem-G. _______________________________________________________________________________ Command Line Switches Defaults: CON Redirect Display Output to CON: Standard Out port n Open DOS COMn: for data inp/out.

(3) The Sender should initiate Zmodem-Batch. After beginning, the Receiver can select to DownLoad File(s) with Zmodem or Ymodem-G Batch protocols - the Sender will adjust. (4) During "free-flowing" Zmodem and Ymodem-G DownLoads, DSZ writes data to the Disk in 1024-Byte Blocks. Performance improves using a RamDisk; above 2400 Baud it is essential. (5) The TeleNet TERMINAL=D1 at LogOn increases transfer speed by suppressing NUL characters in the data stream. (6) The TeleNet SET 1:0,4:2,7:8 command configures PCPursuit for High-Speed, Binary File Transfers: 1:0 - Disables <cr>@<cr> escape to '@' Prompt 4:2 - Minimizes Network Transmission Delays 7:8 - Configures [Break] escape to '@' Prompt (7) The TeleNet SET 5:1,12:1 command establishes Handshaking between DSZ and the TeleNet PAD. It should only be used for Zmodem Transfers. Xmodem & Ymodem are not "free-flowing" Protocols, and so require no Flow Control: 5:1 - Enables XON/XOFF Flow Control from DSZ to PAD 12:1 - Enables XON/XOFF Flow Control from PAD to Host _______________________________________________________________________________ note: Connect to PCPursuit Target City before using "SET" commands. _______________________________________________________________________________ ┌─────┐ ╔═══╡ SAT ╞═══╗ ║ └─────┘ ║ ║ ║ XON / XOFF ║ TELENET ║ XON / XOFF ┌─────────┴─────────┐ ║ ║ ┌─────────┴─────────┐ ┌─────┐ ┌─────┐ ┌──╨──┐ ┌──╨──┐ ┌─────┐ ┌─────┐ │ TTY ╞═══════╡ MDM ╞═══════╡ PAD │ │ PAD ╞═══════╡ MDM ╞═══════╡ BBS │ └─────┘ RS232 └─────┘ 1200B └─────┘ └─────┘ 1200B └─────┘ RS232 └─────┘ └──┬──┘ └──┬──┘ └──┬──┘ └──┬──┘ RTS/CTS MNP outdial RTS/CTS Optimization of TeleNet -
