Sending a file using Zmodem

Hi all,

I'm trying to send a file to a remote host on a DG/UX system connected directly to a serial port of a computer, but every time I try to send the file, the remote host cannot recieve it (the download screen hangs, some wierd characters are displayed when I type the rz command).

I tried using kermit and it starts, gets about 11000 blocks, then stops.

I'm trying to send a binary file about 1.6 gb in size.

Any tips would be greatly appreciated.

Use a program like b64encod and b64decod to change your binary file to a text file, then transmit, and the convert the text file back to binary. The serial port (software) is probably interpreting some of the characters (those below 32) as control characters rather than data. If both machines are unix, you might try uucp as it will transfer binary files.
You are kidding about trying to transfer 1.6gb via a serial port. Even at 112kbaud it will take 1,600,000,000 / 11200 seconds = 2 days. And even if you were able to copy it, the chances of doing that without a single error is improbable.
Just copy the file to a dvd and courier the dvd to the remote site.
