Honeywell BCRU221G
This is another one of the Honeywell serial terminals that were typically used with DPS mainframes, after Honeywell took over the line of GCOS-based mainframes from General Electric. Probably used with DPS6 mainframes (confirmation needed).
Hardware connectivity
A typical db25 serial cable doesn't seem to work, nor does the typical null-modem cable. Instead, following pinout seems to work:
DB25 pinout:
--------------------------------------------------------------------
\ (1 ) (2 ) (3 ) (4 ) (5 ) (6 ) (7 ) (8 ) (9 ) (10) (11) (12) (13) /
\ (14) (15) (16) (17) (18) (19) (20) (21) (22) (23) (24) (25) /
\______________________________________________________________/
1: Shield ground 6: DSR (data set ready) 11: N/C
2: TXD (transmit data) 7: Signal ground 12: DCD (2)
3: RXD (receive data) 8: DCD (data carrier detect) 13: CTS (2)
4: RTS (request to send) 9: test 14: TXD (2)
5: CTS (clear to send) 10: test 15: DCE
16: RXD (2) 21: signal quality detector
17: RX clock 22: RI (ring indicator)
18: N/C 23: data signal rate detector
19: RTS (2) 24: DTE
20: DTR 25: N/C
TXD (pin 2) has data going from the terminal to the computer at 0-5V
TXD2 (pin 14) has data going from the terminal to the computer at 0-1.5V
DB9 pinout:
-----------------------
\ (1) (2) (3) (4) (5) /
\ (6) (7) (8) (9) /

-------------------------------------------------------------------
1 (shield) -> shield (the metal bit around the connector)
2 (TXD) -> 2 (RXD)
3 (RXD) + 16 (RXD2) -> 3 (TXD)
4 (RTS) -> 8 (CTS)
5 (CTS) -> 7 (RTS)
6 (DSR) + 8 (DCD) -> 4 (DTR)
7 (GND) -> 5 (GND)
20 (DTR) -> 1 (DCD) + 6 (DSR)
