- ; This file identifies the I/O port assignments used for Mycroft Doorware
- ; products or any doors compiled using the Mycroft DM Library Version 3.00
- ; or newer.
- ;
- ; Lines starting with a ';' and blank lines are ignored. Other lines are
- ; processed and entered into the port table used by the door program. Ports
- ; not specified in this file use the default values (as described below).
- ;
- ; The format of each entry contains the following entries in the order shown
- ; here:
- ;
- ; PORT - Comm Port ID This field indicates which port is being
- ; defined. It may range anywhere between
- ; COM1 and COM8.
- ; ADDR - I/O Port Address This field identified the physical I/O port
- ; address. This value is expressed as a four
- ; digit hex number.
- ; IRQ# - IRQ Number This field identifies the IRQ (Interrupt
- ; Request) line used by the I/O port. This
- ; value may range between IRQ0 and IRQ7.
- ; ACCS - Access Type This field indicates how the I/O is to be
- ; performed. The following values are allowed:
- ; BIOS - BIOS or Fossil driver
- ; PORT - Direct access to the I/O ports
- ; INTR - Interrupt driven direct access.
- ; HAND - Handshake Flag This field indicates what type of handshaking
- ; the program is to use when communicating with
- ; your modem. This value may be one of the
- ; following values:
- ; NONE - No handshake
- ; SOFT - XON/XOFF handshaking
- ; HARD - RTS/CTS hardware handshake
- ; BOTH - Both XON/XOFF & RTS/CTS
- ; It is recommended that HARD be used. If your
- ; modem does not produce CTS then it is suggested
- ; that you use NONE.
- ; PASS - Pass Through Flag This field indicates whether the IRQ being
- ; used is shared with another device. This field
- ; may be set to either YES to allow interrupt
- ; passthrough or NO to disable it. This field
- ; is ignored if the INTE field is set to NO.
- ; Suggested value for this field is NO unless
- ; you are using true shared interrupts.
- ;
- ;
- ; No defaults are provided for COM5 through COM8 and they must be defined
- ; if they are to be used.
- ;
- ; Defaults for COM1 through COM4 are as follows:
- ;
- ; PORT ADDR IRQ# INTE HAND PASS
- ; ---------------------------------------
- ; COM1 03F8 IRQ4 INTR HARD NO
- ; COM2 02F8 IRQ3 INTR HARD NO
- ; COM3 03E8 IRQ4 INTR HARD NO
- ; COM4 02E8 IRQ3 INTR HARD NO
- ;
- ;
- ; Actual Definitions:
- ;
- ; PORT ADDR IRQ# ACCS HAND PASS
- ; ---------------------------------------
- COM1 03F8 IRQ4 INTR HARD NO
- COM2 02F8 IRQ3 INTR HARD NO
- COM3 03E8 IRQ4 INTR HARD NO
- COM4 02E8 IRQ3 INTR HARD NO
