It's been a long time, but I'm pretty sure that the LA210 has a DTE RS232 interface - like a VT220. If you would expect to use a null-modem connector on your serial port to attach a VT to it, you should do likewise for this printer. Some of the DIP switch settings you may find useful: Switch A: A2 down - Disables modem control A2 up - Enables modem control A6 down - Disables auto-Xon/Xoff A6 up - Enables auto-Xon/Xoff Switch B: Baud Rate: B1 B2 B3 B4 B5* D D D D D 50 U D D D D 75 D U D D D 110 U U D D D 134.5 D D U D D 150 U D U D D 200 D U U D D 300 U U U D D 600 D D D U D 1200 U D D U D 1800 D U D U D 2400 U U D U D 4800 D D U U D 7200 U D U U D 9600 D D D D U 75 T/ 600 R U D D D U 75 T/1200 R D U D D U 150 T/ 600 R U U D D U 150 T/1200 R D D U D U 300 T/2400 R U D U D U 300 T/4800 R D U U D U 600 T/2400 R U U U D U 600 T/4800 R * Switch B5 selects equal (D) or unequal (U) Transmit and Receive rates.
