Driver for serial multi-channel PCI cards based on the Moschip MCS 9900/9912 PCIe controllers.

commoschip [poll[=ticks] pollpri=pri inst={all,0..31} | first=x | list]

Parameters

poll[=ticks]

Enable polling at optional tick rate.

pollpri=pri

Set the priority of the polling thread, default 128.

inst={all,0..31}

All or indicated instances of the card. The default is instance 0.

first=x

Register channels beginning at COM(X). The default is COM9.

list

List supported Moschip devices PCI vendor id, device id, and short description.

Remarks

Channels are installed beginning at the "first" parameter. If that channel is already taken, the channels are installed starting at the first available position. Consequently, care might be taken to ensure that devices of one type are installed in consecutive positions.

Uninstalling a device driver frees the allocated channels for use by other drivers.

Note: MSI is not functional on these devices, so they require a legacy IRQ for interrupt operation.
