dc(7) Miscellaneous Information Manual dc(7)
NAME
dc - serial line/mouse/keyboard
SYNOPSIS
controller dc0 at ibus0 slot 0 vector dcintr
DESCRIPTION
The dc serial line controller provides DECstation 2100, DECstation 3100, DECstation 5000, and DECstation 5100 computer systems with key-
board, mouse, and serial communications interfaces. The serial communications interfaces on the DECstation 2100 and DECstation 3100 provide
partial modem control. The serial communications interfaces on the DECstation 5000 provide full modem control. The device special file
/dev/tty01 on a DECstation 5100 provides full modem control, while the remaining ports provide no modem control at all. All serial commu-
nications interfaces operate at baud rates from B50 to B9600, excluding B200.
The dc ports are used as follows: Usage Graphics device keyboard at 4800 BPS Mouse or tablet at 4800 BPS Communications port 1 (w/modem
control)/local terminal Communications port 2 (w/modem control)/local terminal
On all systems except the DECstation 5100, serial port 2 is used for the system console port in server (that is, non-graphics) configura-
tions. On DECstation 5100s, the serial port labeled 3 on the back of the system is always the system console port. The serial system con-
sole port always operates at 9600 BPS, 8-bits, no parity; modem control is not supported.
RESTRICTIONS
Data communications equipment attached to the console serial port in server configurations must be set to 9600 BPS, 8-bits, no parity. The
scc driver enforces this restriction.
FILES
console terminal local terminal local terminal local terminal (DECstation 5100 only)
