TITLE: ErrMsg: R6003 Integer Divide by Zero Error When Starting Procomm Plus

The information in this document refers to:

 - Procomm Plus, version(s) 2.01

SYMPTOM: You are trying to install Procomm Plus 2.01 on a 200 Mhz Pentium 
machine and you receive the following error:

Run time error R6003 - Integer divide by 0

CAUSE: There is a timing dependent routine in the startup code for Procomm 
Plus that is used to generate timing values for events.  This routine is 
overwhelmed by the very fast processing power of the P6 200 Mhz machine.  The 
result is the error above, and the system usually locks up.

RESOLUTION: This has been fixed for machines up to 200Mhz.. Download the 
patch D2UP0001.EXE from the PCPLUS library on any of our support sites. For 
faster machines you will need to slow down the processor with speed 
controlling software like Moslo (www.hpaa.com).

TITLE: How to Troubleshoot IRQ and BPA Conflicts

The information in this document refers to:

 - All version(s)

SYMPTOM: IRQ Conflict symptoms are as follows:  SD light is locked on RED 
when typing in terminal, unable to see what your typing on the terminal, 
although if you type ATDT you may hear a dialtone, cannot connect to hosts, 
lockups when accessing modem, modem will not dial, Fatal Exception errors, 
cannot send and/or receive faxes, intermittant connections on incoming data 
calls or modem will not answer.  Connections results in garbage or you're 
unable to see prompts.

BPA Conflict symptoms are as follows:  Inconsistencies in connections and in 
receiving responses on AT commands. In order to confirm BPA Conflicts with 
internal modems on COM1 or COM2, deinstall your modem physically by taking it 
out and run DEBUG from DOS.  If DEBUG lists the COM port your modem was 
installed in, you have a BPA Conflict.  

CAUSE: IRQ Conflicts:  Two hardware devices using the same interrupt causes 
IRQ conflicts.  Common mistake, Soundcards usually default to IRQ 5 which is 
what is reccommended for modems on COM3 or COM4.

BPA Conflicts:  Internal modems installed on COM1 or COM2 causes BPA 
conflicts.

RESOLUTION: IRQ Conflicts:  Use an available interrupt with your modem.  In 
Win95 Start | Settings | Control Panel | System | Device Manager | Computer 
will list interrupts that are being used.  COM1 and COM2 interrupts cannot be 
changed from its defaults unless disabled from the BIOS area.

BPA Conflicts:  Disable physical COM ports in the BIOS area or install 
internal modems on COM3.
