SUMMARY

The information listed below describes the COM port settings in the [ports] section of the WIN.INI file as changed by the Flow Control options when selecting Ports from Control Panel.

MORE INFORMATION

When the Flow Control settings on a COM port are saved as xon/xoff, an x is added to the appropriate COM port in the [ports] section of WIN.INI.

For example:

com1:=9600,n,8,1,x

The "x" designates an xon/xoff software handshake.

When the Flow Control settings on a COM port are saved as hardware, a "p" (without the quotation marks) is added to the appropriate COM port in the [ports] section of WIN.INI.

For example:

com2:=9600,n,8,1,p

The "p" designates a hardware handshake and infinite retries.

The absence of a letter at the end of a line donates Flow Control set to none.
