DESCRIPTION
Umodem uses the Christensen protocol to transfer files to and from CP/M systems.
Umodem -- Implements the "CP/M User’s Group XMODEM" protocol, the TERM II File Transfer Protocol (FTP) Number 1, and the TERM II File Transfer Protocol Number 4 for packetized file up/downloading.
There is currently no batch transfer capability. The program writes logging data to a file in the user’s home directory called umodem.log.
The program will do a protocol file transfer with error checking to or from a CP/M system running Ward Christensen’s program MODEM or one of its derivatives (MODEM7 or APMOD777 etc.) or any program that uses the same protocols (e.g. ZPRO, TERM II). Note that executable and squeezed files must use the -sb or -rb options.
Umodem supports an interactive mode in which the user may perform a number of Umodem-oriented functions without leaving Umodem. These functions (and their commands) are:
