     I have many LJ4's connected serially through 3-wire DTC ports at 9600
     baud. On some of the printers, I randomly (not consistently) receive
     '22 SER IO ERROR' on the printer's display. Help! What do I need to
     change to eliminate this error.

     Most of the printers have JetDirect Cards for Netware printing. All
     printers are < 300' from a DTC.

     The errors occur mostly on output containing laser forms. But the
     errors are not consistent. I have another LJ4 serially connected that
     is my heavy-duty laser forms printer and it never receives a '22 SER
     IO ERROR', but it also does NOT have a JetDirect card.

     Any suggestions will be most appreciated!
