Installation ============ Add a DEVICE= statement to your CONFIG.SYS: DEVICE=c:\OS2\BOOT\USBSER.SYS where c: is your boot volume. You must reboot to active the driver. Uninstallation ============== Remove the DEVICE=c:\OS2\BOOT\USBSER.SYS (where c: is your boot volume) from your CONFIG.SYS. Getting Support and Reporting Problems ====================================== For more information and to report problems please visit: https://www.arcanoae.com and click on SUPPORT. Or go directly to the USB support wiki at: https://www.arcanoae.com/wiki/usb/ Driver Command Line Options =========================== Option Description ------------------------------------------------------------------------------ /V Display informational messages during boot. /DCD Forces DCD on for status and causes DCD to be ignored internally. May be required for non-modem connections such as PC to PC links. /Z Forces CTS and DSR on internally. May be required for non-modem or 3 wire connections. /M: Specifies the number COM ports to allocate. Default=1. Currently the maximum limit is 6. /N: Sets the name of the first COM port. Default is first available COM. This driver cannot use a name that is already in use by another driver that was loaded before this driver. If you specified 4 ports starting at COM2, and COM5 is already being used, then this driver will allocate COM2, COM3, COM4, and COM6. If you specify a name without a number such as COM, this driver will start counting at 1 allocating COM1, COM2, ... Names allocated by this driver cannot be used by other drivers in the system. Additional debugging options: /W Causes the debug buffer to wrap. The default is nowrap. /COM: Causes debug messages to be output to the specified serial port. 1=0x3f8, 2=0x2f8, 0xnnnn specifies the COM port base address. /BAUD: Sets the debugging serial Port to the specified speed. Only valid if /COM is specified first. Additional Notes ================ This driver supports up to 16 devices. You cannot load this driver more than once. Example for one device at COM1 DEVICE=C:\OS2\BOOT\USBSER.SYS Example to use 3 serial devices starting at COM5 DEVICE=C:\OS2\BOOT\USBSER.SYS /M:3 /N:COM5 This will allocate 4 COM devices: COM5, COM6, COM7, and COM8. Each recognized USB device will attach to a COM port in the order that they are discovered. Each COM port will only work when a device is attached to it.
