I am assuming that since you said you tried the HP recommended cable that you
have an HP machine. If so you can get it to work on COM3 and or COM4 if you
wish. I am also assuming you are using an HP Ser/Par or dual serial card.
If it is an HP card I don't know how you changed it to IRQ5 (this is also
the IRQ for LPT2) but the configuration shown here requires defaults or
if they are not, then change the entries to match the IRQ's you have set
and the IO addresses you have set.

First add a mode statement in your autoexec.bat for the com port you wish
to use. IE: mode com3:96,n,8,1,p

Then edit your system.ini in your windows directory and add these lines to
the [386enh] section

Com3Base=3e8h
Com3Irq=10
Com4Base=2e8h
Com4Irq=11

Now edit your win.ini file and change or add ...

Change COM3:=9600,n,8,1 to COM3.OS2=

or just add COM3.OS2 in the same section.

Do the same for COM4 if you have and wish to use it.


Then reboot the machine and run windows. Run the control panel and configure
your printer for one of the COMX.OS2 ports you added in your win.ini.
 
I have also seen some folks just add a redirector in thier autoexec.bat
like LPT2=COM3 along with the necessary mode statement and configure windows
to LPT2.OS2 and it seems to work fine as well.


Good luck.
