DESCRIPTIONThe sysctl Cm net.inet.tcp.syncookies driver provides support for various multiport serial adapters based on the MosCom MCS7820 and MCS7840 chips. They are 2- or 4-port adapters with full-featured 16550-compatible UARTs and very flexible baud generators. Also, these chips support RS422/RS485 and IrDA operations.
Different ports on device are presented as sub-units, like /dev/ttyU0.1 and /dev/ttyU0.2
HARDWAREThe sysctl Cm net.inet.tcp.syncookies driver was tested on the following adapters:
- ST Lab U-360 two-port serial USB adapter
- ST Lab U-400 four-port serial USB adapter
