the 2 banks of switches?

0

I use an AE Serial Pro in my IIe to connect to my ImageWriter II. All of the DIP switches are set to OPEN (switch down). The switch block next to the printer interface connector is for hardware handshaking signals. (Copied without any permission whatsoever from the AE Serial Pro User’s Manual.) o Switch 1, when closed, select pin 4 (Request to send) as the flow control handshaking line. Some printers which use this line are: Data General TP2; Heath H-25; Olympia ESW102/103; QUME Sprint 5; and Smith-Corona TP1 o Switch 2, when closed, selects pin 11 which is, according to RS-232-C specifications, undefined and is used by some serial printers as a printer- ready signal. Some Centronics, Texas Instruments, and Epson serial printers may use this pin. o Switch 3, when closed, selects pin 19 (Secondary Request to Send) as the handshaking line. Some of the printers that use this pin are the Anadex DP8000/9000, Bell TP-1000, Lear Seigler 310, NEC 3500/7700, and Digital Equipment (DEC) LA-serie
