NAME
sab, sabtty -- Infineon 82532 Enhanced Serial Communication Controller (ESCC2)
SYNOPSIS
sab* at ebus? sabtty* at sab? channel ?
DESCRIPTION
The sab driver provides TTY support for the Infineon (previously Siemens) 82532 serial communications interface found in many Sun Ultra worksta- tions 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.
NOTES
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.
FILES
/dev/ttyh[0123] serial ports
DIAGNOSTICS
sab*: ring overflow The software input "ring" has overflowed. This usually means input flow-control is not configured correctly (i.e. incorrect cable wiring).
