I am trying to transfer a file from the PC (lastest ICE.TEN) to a Unix File Server (SCO 5.0.6).  I keep getting a timed out error.  I have tried changing the time out settings and buffer setting with no success.

What is strange, I was able to do this a week ago just fine.

Any thoughts would be very much appreciated.

Did the versions of ucopy on either side change (i.e. did you update ICE.TEN on the PC and not the SCO box)?

Any changes on the SCO box (shell, etc)?

Permissions problems (file already exists but is not writable by the user trying to upload)?

[solcon]

The only thing I noticed was the file ownership of dshell and ucopy.  I made sure they were set to root.  Otherthan that, everything looks okay.

However, the same result, time out error.  It stops at the same point. 17 packets with 2% transferred.

17 is suspicious. It's the packet number that's the same as the xon code. It's probably getting intercepted by your multiport board. Try quoted xmodem or quoted ymodem.

I tried quoted-ymdoem and that worked.  Why???  Actually what is quoted-modem?

Thank you for the help.

[Bob]

It avoids the xmodem/ymodem protocol characters that are control codes. It's really working around a bug in the multiport board software. When ucopy on the Unix side goes into raw mode, the multiport board SHOULD pass through the control characters, including xon and xoff. The problem is that yours is NOT passing them through. The quoted protocols work around this by converting all of the control characters to printable characters by "quoting" them.

Thank you for all your help with this problem.
