OS/2 or by the COM.SYS device driver provided by Device Driver Source Kit for
OS/2.
COM.SYS Default Device Driver
The default device driver can only apply to standard COM1 and COM2 ports. It is
active when the system is booted up. Please configure the first and second ports of
the C114HI as COM1 (3F8, IRQ4) and COM2 (2F8H, IRQ3), respectively.
Interrupt vector is not used. Remember to disable the COM1/COM2 on the host if
exist.
COM.SYS Device Driver from Device Driver Source Kit for OS/2
The COM.SYS device driver can support up to 4 COM ports with user-defined I/O
port addresses and interrupt levels. To enable it, a line describing C114HI's
configuration (same as configured in IO-IRQ program) should be added to file
C:\CONFIG.SYS and then reboot the system again.
Syntax:
DEVICE=PATH\COM.SYS (COM#, PORT@, IRQ#, BADINT, FIFO) ...
Where
PATH :
the path of the device driver COM.SYS
COM# :
the com port number (1~4)
PORT@ :
the port's base I/O address
IRQ# :
the IRQ level to use for the port, no IRQ sharing.
BADINT :
what to do for bad interrupt i (ignore), d (disable port), p (post to application).
FIFO :
if this is a FIFO port or not (t or f)
Example:
DEVICE=
C:\COM.SYS (1, 3F8, 4, d, t) (2, 2F8, 3, d, t) (3, 2C0, 5, d, t) (4, 2C8, 7, d, t)
