Ok all you VAX MODEM fans. This little utility (and if you don't know what it is, you probably don't want to) is now available in UTL$EXE. Do the following to use it:- $ VAXMDM:== $UTL$EXE:VAXMDM.EXE It allows aborting by ^X now and the command file is no longer needed to run it. Please use this new version, if you are currently using the old one. A repeat of the help documentation follows. Delete now if you are not interested. VaxModem is a version of the common Xmodem found on RBBS/RCPM systems. It allows uploading and downloading to/from the Vax when dialing in. It is useful for anyone who has the equivalent Xmodem or modem7 etc program on their system at home. Or any system that uses the (standard?) Ward Christensen protocol. (SOH,SEC,COMPSEC,128data,crc). This program will allow transfer of text files or binary files, and can use either CRC or checksums. It is run by either typing VAXMDM and waiting for the command prompt, or typing the command and filename on the command line. $ VAXMDM ? This will give a limited help message. $ VAXMDM s file.dat This will open the Binary file file.dat on the vax and send it to your system. $ VAXMDM sa file.src This will open the text file (Variable length CR), file.src on the vax and send it to your system. $ VAXMDM r file.dat This will create the Binary (fixed length 128 byte) file file.dat on the vax and receive data from your system using CRC. $ VAXMDM rc file.dat This will open a binary file file.dat on the vax and receive data from your system, it will expect a a checksum. Note the c option is only effective for the receive command. It will tell the sending program to use CRC or checksum. The program will prompt you with a message similar to the following:- receiving file file.dat in binary using CRC Hit control X slowly a number of times to abort After getting this message start the transfer, for your machine. Typing control X (usually once) will abort VAXMDM. Install it by:- $ VAXMDM:== $UTL$EXE:VAXMDM.EXE Any problems, let me know. Jim
