Try
Code:
/etc/fuser /dev/tty1a

The output is the pid of any processes using it.

Lock files would be in /usr/spool/uucp, but only if the program using the file is cu, uucp or login/getty

NAME
iscc - serial communications interface SYNOPSIS
controller iscc0 at isa0 DESCRIPTION
An onboard Zilog 8530 DUART provides AXPvme-based Single Board Computers with console (CON) and auxiliary (AUX) serial communications ports. Both serial communications ports can operate at baud rates from B50 to B38400, excluding B134 (see tty(7)). On AXPvme Single Board Computers configured with a graphics head as the system console, the CON serial communications port (/dev/tty01) is available for use by application programs as an additional communications port. In the absence of a graphics head, the CON serial communications port (/dev/console) becomes the system console. When used as the serial system console, the CON serial communications port always operates at 9600 BPS, 8-bits, and no parity. Regardless of system console, the AUX serial communications port (/dev/tty00) is always available for use by application programs. RESTRICTIONS
Data communications equipment attached to the CON serial communications port must be set to 9600 BPS, 8-bits, no parity when configured as the serial system console. The iscc terminal driver enforces this restriction. No modem control is supported for either the CON or AUX serial communications ports. FILES
console terminal local terminal local terminal RELATED INFORMATION
