VSPD PRO offers several options:
Enable baud rate emulation for virtual serial ports
This option allows virtual ports to emulate the data transfer speed of real ports. Equalized baud rate prevents data losses.
Ignore errors when creating bundles
With this option enabled, you can continue the creation/opening process even if some of the port pairs are not created/opened.
Retry opening real port later in case of failure
This option allows reopening serial port automatically in case it doesn’t open at the start (and the "Ignore errors…" option is enabled) or if a serial port was removed while the service was running (USB to COM lead was unplugged).
Make virtual and shared ports available for printers
This option makes virtual and shared ports visible for such peripherals as printers.
