I am unfamiliar with the 1130, and I've never used the 1130 simulator, but
SIMH usually implements Telnet for the console as an option. SET CONSOLE
TELNET=<port> moves the console terminal to a Telnet connection, and SET
CONSOLE NOTELNET reverts it back to the window that started SIMH. See
section 3.12 of the SIMH User's Guide.
Is there perhaps a SET CONSOLE TELNET command in a startup script? (Note
that if there's an "ibm1130.ini" file in the same directory as the
executable, it'll be run automatically at startup.)

A very quick squint at the code in "ibm1130_stddev.c" suggests that the
console should do I/O through the main window. "tti_svc()" is calling
"sim_poll_kbd()", which is the standard input routine, and several other
routines are calling "sim_putchar()", which is the standard output routine.
