(ESCC2)
sab* at ebus?
sabtty* at sab? channel ?
The sab
driver provides TTY support for the Infineon
(previously Siemens) 82532 serial communications interface found in many Sun
Ultra workstations and servers.
Input and output speeds for each line may be set to any baud rate
in the following list: 50, 75, 110, 134, 150, 200, 300, 600, 1200, 1800,
2400, 4800, 9600, 19200, 38400, 57600, 76800, 115200, 153600, 230400,
307200, 460800, 614400, 921600.
The speed cannot be changed on the ports connected the Remote System Control
(RSC) on a Sun Enterprise[tm] 250 Server (ttyh2 and ttyh3). These ports are
fixed at 115200 baud.
- /dev/ttyh[0123]
- serial ports
- sab*: ring overflow
- The software input “ring” has overflowed. This usually means
input flow-control is not configured correctly (i.e. incorrect cable
wiring).
The sabtty
driver first appeared in
OpenBSD 3.1 and was then ported to
NetBSD 2.0.
