I'm getting an error 8002 "Invalid port number" when setting the CommCtl (VB6
SP4) port number property to any number over 16.
I have a modem bank that implements 48 COM ports out of a couple of T-1s.
Article Q142002 mentions the problem but it was last updated on 11/29/00. The
problem is mentioned for VB4. Is there a fix for VB6?

If a fix does not exist, will it work if I use the Win32 API calls, instead of
the control itself?

Please advise urgently

Based on my research, the KB article is also right for VB6. A workaround is
to use a third-party software, such as PDQComm.OCX which is available from
Crescent (203-431-4626) and supports up to 99 comm ports. Using the
Win32API will not have such limitation, but need more effort to write code.
