Hello, everyone in this group!! I have a problem in using X/YMODEM file transfer protocol between my pc and unix. Since I have no manuals(if they exist) and can only tried it based on my limited knowledge of this field, I hope someone here could give me information as regards to these problems. 1. When sending certain files from unix to pc, timeouts were encountered repeatedly. Since they all occurred at a given point for any particular such files, I suspect that there is a sequence of text in the file that caused the protocol to behave differently (i.e, command string). Is my guest correct? 2. I had no luck at all in sending files from pc to unix. After I issued commands respectively between two systems, they both sat still. I used no options in either `rb' or `rx' command at unix side. I sincerely hope someone could give me pointers as where I can get some information concerning these protocols. Since I am not a regular reader of this group, I appologize if such questions have been posted and answered before. Thanks in advance. -- YUNG-KAO HSU, ICS, COLLEGE OF COMPUTING >L me := self deepCopy. hsu@cc.gatech.edu GEORGIA TECH =+ [me boring] ...!{akgua,decvax,ihnp4,ulysses}!gatech!cc!hsu O| whileTrue: [me rn].

I don't know what your specfic problems are, but let me give you two pointers which should always be checked when dealing with [XYZ]modem: o make sure you have a 8-bit path (ie. both the sender and receiver must agree to be using 8 bits. On SYSV UNIX machines this is done by typing 'stty cs8' (or 'stty cs8 -parenb' more often so parity won't be a problem). o make sure that there is no software flow contol happening on either side of the line, since the protocols (especially Zmodem) can handle internally the problems that XON/XOFF are designed to help with. Hope this helps. Peace, dNb
