Driver for USB modems. At the moment support is only available for some devices from IBM and US Robotics. The USBCOM.SYS driver emulates an additional COM port, this allows use of terminal or dialer software with the USB modem.
DEVICE=x:\OS2\BOOT\USBCOM.SYS <parameters>
Parameters
- /N:Value : Here can you control under which COM port number the USB device is available. Value can be in the range from 1 to 9. It had to be a non-used COM port number. The default value is the first non-used COM port number.
- /V : With this parameter gives the driver you some status information during the boot.
- /M:<X> : X = Number of USB Modems to be used at the same time
- /I:<X> : X = Size of Inbuffer in kB
- /O:<X> : X = Size of Outbuffer in kB
- TIP
- By William L. Hartzell: Know that you can assign an alias to the USB port by using /N:COMx at the end of the USBCOM driver line. Thus it becomes useable with software that does not know about USB ports. You will need one driver line per modem.
Examples
DEVICE=x:\OS2\BOOT\USBCOM.SYS
Where "x:" is the drive letter of the OS/2 boot partition on your system.
DEVICE=C:\OS2\BOOT\USBCOM.SYS /M:1 /N:COM8 /V
This one specify one (1) modem with the COM8 port and shows the version information on boot.
