Function and use of serial ports
COM1 as serial console device
Instead of the on-board local bus SVGA, you can use COM1 as the
console device. See the
Console devices chapter for more information.
When COM1 is not used as a console device, then it is available to your
program as a standard RS-232 port. Octagon Systems strongly urges
that you leave COM1 at the 3F8h default address.
COM1 through COM6 as RS-232 I/O
COM1 through COM6 can also be used as RS-232 serial ports. Depend-
ing upon the design of each port, COM1 through COM4 can support
4- or 8-wire configurations, and COM5 and COM6 are 4-wire only
configurations. Use a VTC-20F cable to interface from the PC-510 and
the serial device.
