Syntax

DEVICE=C:\OS2\BOOT\USBSER.SYS <parameter>

Parameters

/V
Verbose mode to display driver information.
/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:<number>

Specifies the number COM ports to allocate. Default=1. The maximum limit is 16.

/N:<name>

Sets the name of the first COM port. Default is first available COM<n>. 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:<port>

Causes debug messages to be output to the specified serial port. 1=0x3f8, 2=0x2f8, 0xnnnn specifies the COM port base address.

/BAUD:<baud>

Sets the debugging serial Port to the specified speed. Only valid if /COM is specified first.

Remarks

This driver supports up to 16 devices. You cannot load this driver more than once.

Samples

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.
