Usually, xmodem at 1200 gives 90 cps, while zmodem can get 110 cps at 1200 baud. Always try to use zmodem, since it can download one file in two parts (if the system crashes during a download, you can start where you left off). At 2400 baud, expect twice the above cps, with a max zmodem of about 240 cps. At most I have gotten 280 cps xmodem and 1760 cps with ymodem (at 19200 baud). Always avoid Kermit (really slow). >modem but still I think I still will have to wait at least a couple of hours >for a file to get downloaded.

Also what to do with files that are longer than 880K. i.e they can't be >put onto one diskheema Always try to use zmodem, or then try ymodem. They are 30% faster and more reliable. If a file is over 800k, then it can be split if it is a disk compressor. If it is a normal archive, then only decompress enough to fit in each disk (or all of it in ram).
