McCullough @Binary Output Start makes your TAC send the TELNET command sequence IAC DO TRBIN, requesting your host to send you 8-bit binary data instead of 7-bit ASCII. The host replies with IAC WILL TRBIN, which turns off padding and suchlike which are normally done by the TAC. @Binary Input Start makes the TAC send IAC WILL TRBIN, telling your host you will now be sending 8 bit binary data, the host responds with IAC DO TRBIN, and the TAC sends 8 bits without intercepting @, etc. The right way to do this is to have it done by the program on the host, so that the user need never know it was even necessary. When the program exits it can send the IAC DONT TRBIN and IAC WONT TRBIN which correspond to the TAC commands @Binary Input End and @Binary Output End, restoring the TELNET connection to a normal state. Modem programs typically check to see if the user is on a TELNET connection and do this, and double all hex FF data characters so they won't be taken as IAC's by the arpanet. I just logged into the MIT-TAC and it asked me for a password, after telling me a guest password to use. When real passwords are installed in a month or so I fear that's the last y'all will be hearing from me. Anyone have UUCP for the Mac yet? --Devon
