The Port Finder package now includes a Port Finder device driver which
is called PF.SYS. This device driver is loaded from your CONFIG.SYS
file which is located in the root directory of your boot disk (either
A: or C: drive). To use PF.SYS add the following line to your
CONFIG.SYS file.
device=d:\path\PF.SYS [parm1] [parm2]
where d:\ is your boot disk (either A:\ or C:\)
path\ is the directory where PF.SYS is located (can be ommitted if
located in the root directory of boot disk)
[parm1] [parm2] are optional parameters, they are:
C12 = Swap COM1 and COM2 ports
C13 = Swap COM1 and COM3 ports
C14 = Swap COM1 and COM4 ports
C23 = Swap COM2 and COM3 ports
C24 = Swap COM2 and COM4 ports
C34 = Swap COM3 and COM4 ports
If PF.SYS is located in the root directory of the C: drive you would
simply enter any where in your CONFIG.SYS file (or before another
device driver that can use COM3 or COM4) the following line (In addition
if you wanted to swap the COM1 and COM3 ports add the c13):
device=c:\pf.sys c13
You can still use PF.COM to swap both COM and LPT ports. PF.SYS and
PF.COM activate COM3 and COM4 the same and one is not better than the
other. If you do have a COM3 or COM4 port you should either have
PF.SYS loaded in your CONFIG.SYS file or PF.COM in your AUTOEXEC.BAT
file. You need not have both. PF.SYS is only REQUIRED if you are
loading another device driver in your CONFIG.SYS file that can use
either COM3 or COM4, then the PF.SYS file should be loaded before
that device driver.
