Hmmmm... let me see if I understand what you have asked. You purchased a Model 2000 (one of the many almost-but-not-quite MS-DOS compatibles from the early 80's). You say you can transfer .DO files (ASCII) from your laptop to your desktop but not from your desktop to your laptop. And, that you think it all has to do with the transfer protocol. Also, you have tried xmodem and ymodem to/from this system with your 2000 without success. Note: I'm avoiding the use of upload and download because most get these terms confused. The terms up and down refer to sending and receiving, respectively. Well, let's see... first off, there are two different mathmatical methods used in xmodem. One is CRC and the other is Checksum. A CRC xmodem program will not mate to a checksum xmodem program. That "might" be one item to explore in your use of xmodem. Another point to make is you say that you can go from your laptop to your desktop but not the other way around because you don't have an ASCII protocol available. Well, if I understand this correctly, you issued a command on your 2000 to "capture to a file" incoming data (ASCII) from your laptop. Given that fact, you might have a command available to "send from" a file, just like you "received to" a file. The "send" equates to sending ASCII. I'll stop here. Explore the "send" feature on your Model 2000 and report your findings. It's been far too long since I played with a Model 2000, so other then using general terms, I am SOL with specific details associated with that particular equipment and programming. -Rick-
