This is the help for vth. available commands are: start commences connection between your terminal and the modem. This connection is broken when you type the COMMAND_CHARACTER, which is initially set to character one, control A, and can be changed by the escape command. escape allows you to change the escape character. vth will type out the present value (numerically) and you will be asked to type in a new value, also numerically. @ starts reading commands from the named file. These command files do not nest. If the file contains a SEND= command, then after the file is transfered, you will be placed in == mode, rather than transparent mode. Therefore you can have a command file to send several files. vms spawns a subprocess for you wait allows you to specify a delay for each line, for the send command. The value is an integer, expressed in hundredths of a second. (eg. 550 means 5.5 seconds) restart goes into transparent mode with out reseting modem. This command is meant to be used if you are allready on a remote machine, and you wish to turn the logfile on or off. logfile= turns on the logfile feature. The rest of the command line (after the =) will be taken as a file name, and a record of everything you do will be put into that file. uline causes all input to the logfile from your terminal to be underlined. so that the log file will be appropriate for documentation of a terminal session. PLEASE NOTE that it requires halfdup to be activated, and the remote machine to be set to no echo. In full duplex mode, the command file is only made up of output from the other machine, including the echoing. Since the program does not know which output is echoing, and which isn't you must use halfdup mode. Additional ramifications are that vth will supply echoing, but if you do type-ahead, it will appear, as soon as you hit the key, not when actually used, and the logfile will be exactly what you see on your screen. Control characters will be echoed literally, except for delete, which is processed correctly. nouline turns off uline feature (see above) send= starts sending a file to the other machine. The rest of the command line is the file name. What you should do is first log on to the machine, and get into an editor with insert mode, then type control-A, then issue the send command, and wait for a message that it finished. If you want to abort, type another control-A, and issue the ABORT command. sync used to set synchronization character, The synch character is used by the send command to make sure that vth doesn't transfer stuff too quickly. vth waits for a synch character after sending each line (and the with it). The synch character is initially linefeed, which should be okay. This might not work well if you are transfering a file with embedded control characters. (eg. runoff output) abort abort file transfer (see above) close turns off the logfile, and closes the file. help lists this file on your terminal quit stops program, before using the quit command it is VERY IMPORTANT THAT YOU HANG UP THE PHONE, that is done by typing ^q^u^i^t at any time. After typing the ^quit sequence, you must wait for the message "NO CONNECTION", and the prompt "BIZCOMP:", then, and only then is it safe to type the escape character and issue the quit command. You will get a message "vth termination", Between the time you attempt to hang up the phone, and the time that the connection is actually broken, garbage characters will be put on the line in both directions, but that should be okay, because you will be logged off by that time. NOTES: when you issue the start command, there will be a delay before you go into transparent communication with the modem. During that period typeahead is disabled, and any characters you typeahead will not be echoed, and will be thrown away. After going into transparent mode, you will be prompted by the bizcomp intelligent modem for a command. Usefull commands include: D => dials the number, if busy, or no answer, it sends the message 'NO CONNECTION' to your terminal. If that happens, either issue another D command, or type the the control character, and issue a quit command. command. R => same as D, except it retries if busy or no answer. Pressing a key will abort either command. If no number is given, (ie. R or d is typed) the last number used will be used again. N => displays last number used. There are several other commands, DO NOT USE THEM!!!! THE OTHER COMMANDS COULD CHANGE THE ESCAPE SEQUENCE ACCIDENTLY, OR DO OTHER THINGS WHICH COULD RESULT IN THE PHONE BEING IMPOSSIBLE TO HANG UP. Remember, only issue the quit command if the last thing you got before typing the escape character was the "BIZCOMP:" prompt. LESS IMPORTANT COMMANDS: halfdup makes vth echo everything you type back to you, presumably, for use on a half duplex machine. fulldup turns off echoing, true by default when program starts odd makes all characters sent to the modem have odd parity even makes all characters sent to the modem have even parity none makes all characters sent to the modem have zero parity ones makes all characters sent to the modem have set parity bits nofill makes vth swallow fill characters fill turns off fill feature (vth never generates fill characters) This file is drb3:[morris.termio]vth.hlp
