I've seen the claim made that Red Ryder does not support unattended file transfers initiated by a remote computer. This is not correct. Red Ryder can be set in a passive mode in which it will receive *or send* a file (using Kermit, Xmodem, or straight ASCII) in response to commands coming in over the modem line. This is a documented feature of all versions since 4.0 (at least). Fred Wamsley ihnp4!sol1!s255

It's true that in Host Mode Red Ryder can receive files passively. However, this is done in an idiosyncratic way. In particular it is not done as Dennis Brothers suggested in his MacBinary proposal. Instead, to do a sender-initiated XMODEM transfer to Red Ryder, the sender must first send it the command "RECX filename". RR responds with "Ready to Receive...", which the sender must ignore. Finally it starts sending out NAKs until the transfer begins. Now I'm sure this way of doing things works fine when you only have to send files to Red Ryder. But it sure makes life difficult for the sender, if it doesn't know what kind of terminal program is on the other end. I would strongly urge anyone writing a terminal program in the future to avoid such idiosyncrasies and to accomodate Brothers' proposal to let "ESC b" initiate a MacBinary transfer (and for backward compatibility, to let "ESC a" initiate a MacTerminal transfer.) -- -------------------- David Fay AT&T Bell Laboratories Naperville, IL 60566 ihnp4!ihexp!dafa
