I am getting ready to start working wit the CCS  C compiler, that have
 the capability of compiling functions that could send and/or receive character
 strings from  one or two I/O pins to a PC  RS232 port.
        I understand that CCS will also provide a small program to work on a
 window of the PC display, that will show what s going on that serial port
 between the computer and the target PIC.

        Problem is that I am not able to implement a free COM serial port to
 talk to the PIC due to;


        As my PC is fully loaded, I have already COM1 dedicated to the mouse,
 COM2 to the parallax clearview XX, and an internal modem using COM3 and IRQ 5,
 I am not finding how to implement the COM4, that I need in order to have it
 talking to the target PIC, or actually to the clearview that will be used to
 simulate the target PIC. ( configuration above is already taking over IRQ's 3,4
 and 5.).

        Other solution could be that the pentium motherboard ( award BIOS ) I
 have,  has a separate PS/2 type mouse connector, but is not working all right.
 Have already tried different mouse devices ( IBM PS/2 and also Microsoft
 compatible, ) and also  have tried two different mouse drivers ( IBM and MS
 V9.0 ).
As the Taiwan type manual does not say a word on how to setup, neither do the
 initial setup screens , I imagine that just connecting the mouse to the
 motherboard and loading a mouse driver, specifying a PS/2 type on the command
 line ( C:\mouse\mouse.exe  /Z ), should make the mouse works.
        It does somehow, as follows;
        a. The screen arrows follows the mouse vertical movements, with high to
 much sensitivity, and disappearing when the top or bottom of the screen is
 reached.  ( The mouse adjustments has no effect on the exaggerated sensitivity)
        b.The arrow do not follow any horizontal mouse movement.
    As I said before have already swapped mouse and mouse drivers.

any hints on either how to implement an extra COM port and/or how to set the
 mouse port operational, which are not a totally proper questions for this list,
 or maybe somebody has a working project using a 2X16 liquid Crystal display or
 similar and a small keyboard ( calculator type) with a 16C84 or similar that
 could be set to work in a few hours, to receive the messages from the PIC and
 display them ( 2 lines ) and also read the keys ( numeric kbrd should be enough
 ) and send then to the PIC. Anybody has that code tested and available??

all suggestions will be highly appreciated and sorry for the long note
