2 CPM Utilities for 8080 etc. Microcomputers running the CP/M operating system. Note especially RCPMLIST.032 is a list of public CP/M systems available over the phone. XMODEM will allow MODEM7 compatable programs to transfer binary or ASCII files to or from your CP/M system with CRC or checksums. CTOV converts CP/M ASCII files as received to VAX editable form (1 line per record, no CRLF at ends of records). VTOC converts normal VAX text files to CP/M format (128 character records, CRLF at ends of lines) ready for transfer. 3 XMODEM Format: XMODEM option file The current options are S Send ANY File from the VAX ST Send a VAX/VMS Text File (file is internally converted to CP/M format) SC Send ANY file from the VAX using CRCs R Receive ANY File to the VAX RT Receive a VAX/VMS Text File (file is internally converted from CP/M format) RC Receive ANY file to the VAX using CRCs Assuming you have MODEM7 runnable on your system, and a direct or modem connection to the VAX, then to perform a transfer using MODEM7 or its successors you would on your CP/M system: A>modem7 you run MODEM7 on your CP/M system Command: T you tell it to emulate a VAX terminal press return to get VAX prompt Username:JIMMY log in to VAX via MODEM7 Password: just as if you were on a direct terminal Welcome... $ xmodem s ulib:[cpm]help.com run XMODEM telling it to send the named file from the VAX CTRL-E gets attention of your MODEM7 program Command: r help.com tell MODEM7 to recieve the file on your CP/M system To send a file to the VAX: $ xmodem r spec34a.dat tell XMODEM to receive file CTRL-E get attention of MODEM7 Command: s spec34a.dat tell MODEM7 to send file to VAX 3 CTOV Converts from CP/M file (continuous stream of bytes in 128 character records with embedded CR LF) to VAX editable file (one line per record carriagecontrol='LIST'). Format: CTOV infile outfile Example, assuming you have accessed the VAX via your CP/M system's MODEM7 program: $ XMODEM R thesis.cpm tell XMODEM to receive the file CTRL-E get MODEM7 attention Command: S thesis.cpm tell MODEM7 to send the file. $ CTOV thesis.cpm thesis.doc convert to VAX text form 3 VTOC Converts from VAX text file (one line per record, no CR LF) to CP/M form (one line per record, CR LF added at end of line) ready for transfer to CP/M system using XMODEM. Format: VTOC infile outfile Example, assuming you have accessed the VAX via your CP/M system's MODEM7 program: $ VTOC thesis.doc thesis.cpm convert to CP/M form $ XMODEM S thesis.cpm tell XMODEM to send the file CTRL-E CTRL-E to get MODEM7 attention Command: R thesis.cpm tell MODEM7 to receive the file. 3 SEND The XMODEM.COM file creates the SEND command as a special form of the more general-purpose XMODEM command. SEND is used to send a Text File from the VAX to the micro. It is equivalent to XMODEM ST. 3 RECV The XMODEM.COM file creates the RECV command as a special form of the more general-purpose XMODEM command. RECV is used to receive a Text File on the VAX from the micro. It is equivalent to XMODEM RT.
