COM1
COM1 is either a full 8-wire RS-232 (standard) or an industrial 4-wire
RS-232 (optional) configuration. The I/O address for COM1 is 3F8h
(default) but can be changed in SETUP to any of the addresses in the
table below. Refer to the
SETUP programs
chapter for more informa-
tion on running SETUP. IRQ4 is dedicated to COM1 and if COM1 is
not used under interrupt control, IRQ4 may be used by other resources.
For example, when COM1 is the console, COM1 uses IRQ4. COM1 can
be used for console I/O or RS-232 I/O. COM1 and COM2 share the J7,
20-pin header. See the chapter on
IRQ routing and opto IRQs
for more
details.
