33 .Nd Infineon SAB82532 (ESCC2) serial communications driver
43 SAB82532 (ESCC2) serial interface chip used in PCI-based UltraSPARC
46 The ESCC2 provides two independent input/output channels per instance.
47 These chips are normally used to provide RS-423 and RS232 serial ports
48 for general purpose use.
52 driver supports all of the standard
55 The status of the DTR, RTS, CTS, and DCD signals can be queried with
56 TIOCMGET command, but, due to limitations in the hardware,
57 only the DTR and RTS signals can be modified with TIOCMSET, TIOCMBIC,
62 .Bl -tag -width /dev/ttyh[0-1] -compact
73 driver first appeared in
78 does not support cua minor devices.
