Just out of curiousity, how many people use SCO CGI in the development of their everyday applications? I don't see much discussion on it and I know it has saved me TONS OF HOURS of re-development time for screen/printer/laserjet graphs etc. I have a question in regards to users of SCO CGI as well. I have several programs (one that is especially detailed is the biggest culprit) that allow me to print a wonderful graph on the ega screen, epson80 printer, and on the laserjet. However, on the laserjet I get one problem. It appears to be lost data as the report commonly gets a strange character on the left side of the page and will mis-place the dots on a row of the graph. Upon the beginning of the next line things appear to go well again. It seems that perhaps a character or two is being lost every few pages. The problem is re-producible and but will move about the page when graphing different data. Some pages/graphs come out fine, others messed. The epson printer and ega screen both look fine here. My guess would be it's a serial link problem -- perhaps with my drivers.? It ALWAYS occurs in the same spot on the same graph, which would leave me to believe its either cgi or a buffer getting full that will always get full at the same position. I guess I could just use a pointer or two as to where to look next. Next alternative is to move the laser printer over to a parallel port and see if the problem is eliminated. If this does it, what do I do to fix the problem (if anything??) On a related note: I have a Digiboard 16i that I'm trying to connect a serial printer to. I've had this printer connected to an Arnet (on another machine) for quite some time. So far I've had much success with the Digiboard as far as I/O goes. However for some reason the printer doesn't appear to want to flush it's buffers when finished with a report. Basically, when I ask to print a printout that's 2304 characters long (just over a page) I get the first page of output from the laser, and can kick the 2nd page out if I tell the printer to eject page. However I will be missing the last line or two. I figure this is probably the remains of a buffer that isn't flushed. Any ideas/quick fixes???
