Steve, NO!! You only need 1 ^F to speed things up. Not only does multiple ^F's have a tendency to cause CIS to quit the download, it will cause it to continue to send blocks for quite a while if you have a failed download causing strange things to occur on the screen. The terminal program sends a ^F for each good block, by you adding 1 to the line (and 1 only) it is already "waiting" at the sending terminal's input so it starts the next block very quickly. During the next block send, the "real" ^F from you program arrives and it is now waiting at the sending terminal's input. Packet switched networks are by their very nature, not optimized for protocol transfers such as Xmodem…so doing a normal Xmodem transfer at 1200 baud actually works out to about 600-700 bps (baud). Doing a turbo transfer works out to be about 1180 bps…which is the same rate you'd get if you were connected to a local BBS at 1200 bps where there is no packet switched network in the middle. Don
