"tq" is a tape drive, I think, so the thing to do would be to find the tape emulation code where that message is being reported and stick some breakpoints into the spot where that happens. The message you're seeing is for the Unix error code EAGAIN, which normally shows up with non-blocking I/O -- if the operation would have resulted in blocking, you get EAGAIN instead if you asked for non-blocking mode. For example, a read when the data isn't available yet. This may be a case of setting non-blocking mode but not handing the resulting error returns correctly in all cases. paul On Jul 26, 2013, at 10:07 AM, Cory Smelosky wrote: On 26 Jul 2013, at 10:05, Paul_Koning <Paul_Koning at Dell.com<mailto:Paul_Koning at Dell.com>> wrote: If you dropped into the simh prompt, that would make it a simh bug.

Need help with VT220 down-line loadable characters (DECDLD)

Sorry, I meant: http://www.vt100.net/docs/vt220-rm/table4-9.html ...since you said vt220.

Announcing DEC Legacy 2013, October 19th/20th, Marchesi Centre, Windermere

by mark＠wickensonline.co.uk

With Johnny's gracious permission: DEC Legacy is back! To be held on October 19th and 20th 2013 at the usual venue, The Marchesi Centre, in Windermere, Cumbria, UK. More details on the website: http://declegacy.org.uk Registration is now open, please follow the Registration tab at the top of the page. Last time the event was opened to anyone with an interest in the highlights of 20th Century computer technology - this provided an interesting mix of hardware from a variety of manufacturers. I would like to continue the event in this vein. So if you own interesting hardware, whatever the origin, we would love to see you at the event. There will hopefully be a couple keynote speakers this time as well, to be announced. Please feel free to forward this email to anyone who might have an interest. I look forward to catching up with familiar faces and making some new acquaintances. Regards, Mark.
