If anyone has the documentation foran Apple Super Serial card
handy, can you tell me what each of the DIP switch settings
mean, especially those regarding the handling of interupts.
Also if anyone is familiar with the Grappler printer interface,
what is the command set to dump graphics page 1?
Thanks in advance,

The handy-dandy ref card in the back of the manual is BIG and chock full of info. To use the card in communications mode, turn SW1-5,6 ON. Once in Comm mode, then: SW1-7 controls RS-232-C signals. SW2-6 controls interrupts SW1-1 to SW1-4 control baud rate (most comm progs override this setting, tho) SW2-1,2 control data fromat (# bits/char, # stop bits - usually overridden) SW2-3,4 control parity (usually overridden) SW2-5 controls whether to send a LF after CR Alot of the other functions of the card are controlled strictly by software. To turn on printer mode, SW1-5 OFF and SW1-6 ON. Once in printer mode: SW1-5,6 ON OFF for SIC P8 emulation (don't know what that means) SW1-5,6 OFF OFF for SIC P8A emulation (ditto) SW1-7,2-7 ON OFF for normal clear to send SW1-7,2-7 OFF ON for secondary CTS SW2-1 ON for 8 data,1 stop; OFF for 8 data 2 stop SW2-3,4 control line width/video: ON ON for 40/video on ON OFF for 72/off OFF ON for 80/off OFF OFF for 132/off SW2-2 OFF for no delay after a CR, ON for 32ms delay after CR other switches are the same as comm mode Hope that helps Dave Whitney Third year undergraduate student in Computer Science at MIT dcw@athena.mit.edu ...!bloom-beacon!athena.mit.edu!dcw dcw@goldilocks.mit.edu I wrote Z-Link.
