Has anyone successfully hooked up an IBM 3812 pageprinter to an IBM RT 6150? I have the special cable which hooks up to the RS232C DB-25 port on the printer to the 10 pin DMA RS232 serial port on the back of the RT. I've created the device, and information does get output through the cable when I cat into /dev/lp0, but I can't make the pageprinter print anything. I have a large file that IBM supplied for printing from an IBM PC, and when I cat it into /dev/lp0, information gets sent through the cable for about a minute, and then I get my prompt back, but nothing comes out of the printer. I have a Synchronous Modem Eliminator that I can stick on the cable, which causes the "online" light, as well as the "ready" light, on the pageprinter to light up. However, cating a file into /dev/lp0 with the SME hooked up causes a "/dev/lp0: No such device or address" message to come up after a few seconds. I know the printer works, because the test printing functions work. The cable works, also. Does anyone know what might be wrong? Do I need a new disk for the 3812?

Use the 'devices' command to configure the port as a printer port. Select 'printer' from the list of device types, and take it from there. You have to select the type of printer and type of connection (rs232, rs422, parallel, whatever). There are several more screens of options that don't have much to do with work/don't work issues. -- Chuck Karish karish@mindcraft.com Mindcraft, Inc. (415) 323-9000
