Technical Configuration (T1/E1)
17. Set Baud Rate. The Connection option in the sidebar menu has a "Settings"
item that includes the baud-rate setting for the COM port of the computer running the
MultiVOIP software.
First, it is important to note that the default COM port established by
the MultiVOIP program is COM1. Do not accept the default value
until you have checked the COM port allocation on your PC. To do
this, check for COM port assignments in the system resource dialog
box(es) of your Windows operating system. If COM1 is not available,
you must change the COM port setting to COM2 or some other COM
port that you have confirmed as being available on your PC.
The default baud rate is 115,200 bps.
