I am trying to establish a UUCP drop with a remote site via modem. I can log on and the remote site can send me messages without any problem at all. However, when I try to send to them, I get numerous data packet errors and timeouts, and usually the software on my end gives up after a while. (Sometimes it does eventually punch a message through.) Now, I had thought that my problem might be the fact that I must go through a communications server at the other end and it was munging things for me somehow. The answer in the above message suggests that it might be my own modem that is the sucker. But, why does transmission (and the associated acknowledgements) work one way and not the other? What is the usual (Hayes) command for modem transparency for my modem.
