_R_Z_S_Z._Z_O_O includes a ZCOMM/Pro-YAM/PowerCom script _Z_U_P_L._T to upload
the small (178 lines) YMODEM bootstrap program _M_I_N_I_R_B._C without a
file transfer protocol. _M_I_N_I_R_B uses the Unix stty(1) program to set
the required raw tty modes, and compiles without special flags on
virtually all Unix and Xenix systems. _Z_U_P_L._T directs the Unix
system to compile _M_I_N_I_R_B, then uses it as a bootstrap to upload the
rz/sz source and manual files.

The PC-DOS OOOOppppuuuussss and NNNNoooocccchhhhaaaannnnggggeeee bulletin boards support ZMODEM.
Integrated ZMODEM support for the CCCCoooolllllllliiiieeee bulletin board program is
planned.
A number of other bulletin board programs support ZMODEM with
external modules (DSZ, etc.).
The PC-DOS Teleconferencing system IIIINNNN----SSSSYYYYNNNNCCCCHHHH uses ZMODEM.
The LAN modem sharing program LLLLiiiinnnneeee PPPPlllluuuussss has announced ZMODEM
support.
Other PC-DOS communications programs with ZMODEM support modules
include QMODEM and BOYAN. Many programs are adding direct ZMODEM
support, including Crosstalk Mark IV, Telix 3.0, and (expected)
Procomm and Qmodem.
The ZZZZMMMMDDDDMMMM communications program by Jwahar Bammi runs on Atari ST
machines.
The OOOOnnnnlllliiiinnnneeee!!!! program for the Amiga supports ZMODEM.
The Compuserve Information Service has ported the Unix rz/sz ZMODEM
programs to DECSYSTEM 20 assembler.

_D_S_Z is a small program that supports XMODEM, YMODEM, and ZMODEM file
transfers. _D_S_Z is designed to be called from a bulletin board
program or another communications program. It may be called as
dsz port 2 sz file1 file2
to send files, or as
dsz port 2 rz
to receive zero or more file(s), or as
dsz port 2 rz filea fileb
to receive two files, the first to _f_i_l_e_a and the second (if sent) to
_f_i_l_e_b. This form of _d_s_z may be used to control the pathname of
incoming file(s). In this example, if the sending program attempted
to send a third file, the transfer would be terminated.
_D_s_z uses DOS stdout for messages (no direct CRT access), acquires
the COMM port vectors with standard DOS calls, and restores the COMM
port's interrupt vector and registers upon exit.
Further information on _d_s_z may be found in _d_s_z._d_o_c and the ZCOMM or
Pro-YAM user manuals.

The Unix _r_z/_s_z programs support YMODEM as well as ZMODEM. Most Unix
like systems are supported, including V7, Sys III, 4.2 BSD, SYS V,
Idris, Coherent, and Regulus.
A version for VAX-VMS is available in VRBSB.SHQ, in the same
directory.
