By default, all Windows 95/98/NT4/2000/ME/XP releases allow only up to 9600 bps on all serial ports: COMx = COM1—COM9 [BIOS (hardware) ports: COM1—COM4 ; Virtual (emulated) ports: COM5—COM9]. These settings enable serial (analogue) modem throughput
over 9600 bps, to possibly speed up Internet access.

Modify the default String Value of the port. For example, COM1 is “9600,n,8,1” by default; you can modify it to “921600,n,8,1,p”.
WARNING: Do this ONLY IF using dial-up (analogue) modems (e.g. 56K, ISDN) connected ONLY to a Serial Port (COMx), NOT IF using xDSL, Cable, Satellite, CNR, USB or Network (digital) modems! If using internal modems located in the Communication Networking Riser (CNR) slot, do NOT use these settings! Such cards are incompatible with these settings. Also, please don’t expect your Internet access speeds to improve—if they do, well and good!
