Unless someone else beats me to it, I will attempt to answer your symbol 17 question later once I have had time to investigate.

Normally plsc->dev_unicode = 0 and plsc->dev_unicode = 1 should be set only by drivers and not by code outside drivers because it indicates whether the driver is implemented for Hershey fonts or modern fonts. Thus, when you forced the issue by setting plsc->dev_unicode = 0 for a driver that had specified plsc->dev_unicode = 1, I am not surprised you got crashes. Of course, it should be relatively trivial to implement Hershey capability as an option for any driver that is currently advertises itself as plsc->dev_unicode = 1. For example, I think this has actually occurred for the gcw device. However, I would view that as a retrograde step since in general, modern fonts have many more glyphs available than Hershey fonts. Thus, I would prefer to fix any problems (e.g., the symbol 17 problem you just found) when using modern fonts. Alan __________________________ Alan W.
