Hello, I have a Cyclades-16Ze connected to a FreeBSD 4.4-RELEASE-p36 system (according to the Cyclades FAQ, as of May 16th, 2003, FreeBSD 4.4 is the latest version that Cyclades supports and there are plans to support higher versions). My intent is to connect a bunch of dumb terminals at 38400 bps and use this system for a series of UNIX/Perl training classes. Unfortunately, I'm having trouble verifying basic operation of the Cyclades using the provided DCE cable and loopback module. I've typed up as much information as I could below to describe what I'm seeing. If you have had any luck getting a Cyclades Z-Series multi-port serial board to work with FreeBSD, I'd love to hear about what you had to do to get things working. I have followed the FreeBSD installation instructions in cz-2.1.1 (the driver provided by Cyclades), and according to dmesg(1), the Cyclades cz0 driver appears to have loaded correctly: $ dmesg | grep '^cz' cz0: <Cyclades Cyclom-Z Adapter> port 0xdc00-0xdc7f mem 0xff000000-0xff0fffff,0xff100400-0xff10047f at device 14.0 on pci0 cz0: Cyclades Ze Adapter. Driver Version 211. Firmware Version 334. cz0: 16 ports detected. Using INTERRUPT mode. Using BOARD RAM. cz0: driver is using old-style compatibility shims When I run kermit-8.0.209_1, I can connect to /dev/cuaC01 (port #2) and view the comm settings: # With Cyclades provided loopback connector removed: Communications Parameters: Line: /dev/cuaC01, speed: 9600, mode: local, modem: generic Parity: none, stop-bits: (default) (8N1) Duplex: full, flow: rts/cts, handshake: none Carrier-watch: auto, close-on-disconnect: off Lockfile: /var/spool/lock/LCK..cuaC01 Terminal bytesize: 8, escape character: 28 (^\) Carrier Detect (CD): Off Dataset Ready (DSR): Off Clear To Send (CTS): Off Ring Indicator (RI): Off Data Terminal Ready (DTR): On Request To Send (RTS): On # With Cyclades provided loopback connector attached (so I know I # have the right port): Communications Parameters: Line: /dev/cuaC01, speed: 9600, mode: local, modem: generic Parity: none, stop-bits: (default) (8N1) Duplex: full, flow: rts/cts, handshake: none Carrier-watch: auto, close-on-disconnect: off Lockfile: /var/spool/lock/LCK..cuaC01 Terminal bytesize: 8, escape character: 28 (^\) Carrier Detect (CD): On Dataset Ready (DSR): Off Clear To Send (CTS): On Ring Indicator (RI): Off Data Terminal Ready (DTR): On Request To Send (RTS): On Unfortunately, when I connect to the port with the loopback connector attached and type, I get no response. More than that, kermit seems to hang (the 'CTRL-\' escape does not work) and I am forced to kill it with a SIGHUP (killall -1 kermit). If I add the appropriate line (cuaC01:dv=/dev/cuaC01:br#9600:pa=none:) to /etc/remote, I can use tip(1) to connect to the port and characters that I type are echoed back to me, but the last character typed does not show up. In this example, I've typed "abc", but only "ab" shows up: # tip cuaC01 connected ab So I have some concerns about basic functionally, but what I really want to do is run a getty on all 16 ports and connect terminals up to them. I've tried adding lines to /etc/ttys that look like this (and running 'init q' to start the gettys): ttyC00 "/usr/libexec/getty std.9600" vt100 on insecure ttyC01 "/usr/libexec/getty std.9600" vt100 on insecure ttyC02 "/usr/libexec/getty std.9600" vt100 on insecure ttyC03 "/usr/libexec/getty std.9600" vt100 on insecure ttyC04 "/usr/libexec/getty std.9600" vt100 on insecure ttyC05 "/usr/libexec/getty std.9600" vt100 on insecure ttyC06 "/usr/libexec/getty std.9600" vt100 on insecure ttyC07 "/usr/libexec/getty std.9600" vt100 on insecure ttyC08 "/usr/libexec/getty std.9600" vt100 on insecure ttyC09 "/usr/libexec/getty std.9600" vt100 on insecure ttyC0a "/usr/libexec/getty std.9600" vt100 on insecure ttyC0b "/usr/libexec/getty std.9600" vt100 on insecure ttyC0c "/usr/libexec/getty std.9600" vt100 on insecure ttyC0d "/usr/libexec/getty std.9600" vt100 on insecure ttyC0e "/usr/libexec/getty std.9600" vt100 on insecure ttyC0f "/usr/libexec/getty std.9600" vt100 on insecure I have connected a RJ-45 to DB-9 Female, Crossover that is configured as follows to another FreeBSD system (running kermit and acting as a dumb terminal): RJ-45 DB-9 Cyclades F/M -------- -------- 3 TxD ------------ RxD 2 6 RxD ------------ TxD 3 4 Gnd ------------ Gnd 5 2 DTR --------|--- DCD 1 |--- DSR 6 7 DCD ---|-------- DTR 4 8 DSR ---| 1 RTS ------------ CTS 8 5 CTS ------------ RTS 7 When I display the communications setting in kermit on the second system, here's what I see: # With the cross-over cable disconnected Communications Parameters: Line: /dev/ttyd0, speed: 9600, mode: local, modem: generic Parity: none, stop-bits: (default) (8N1) Duplex: full, flow: rts/cts, handshake: none Carrier-watch: auto, close-on-disconnect: off Lockfile: /var/spool/lock/LCK..ttyd0 Terminal bytesize: 8, escape character: 28 (^\) Carrier Detect (CD): Off Dataset Ready (DSR): Off Clear To Send (CTS): Off Ring Indicator (RI): Off Data Terminal Ready (DTR): On Request To Send (RTS): On # With the cross-over cable connected Communications Parameters: Line: /dev/ttyd0, speed: 9600, mode: local, modem: generic Parity: none, stop-bits: (default) (8N1) Duplex: full, flow: rts/cts, handshake: none Carrier-watch: auto, close-on-disconnect: off Lockfile: /var/spool/lock/LCK..ttyd0 Terminal bytesize: 8, escape character: 28 (^\) Carrier Detect (CD): On Dataset Ready (DSR): On Clear To Send (CTS): On Ring Indicator (RI): Off Data Terminal Ready (DTR): On Request To Send (RTS): On Unfortunately, when I connect to the port and hit 'enter', I don't get a login prompt and nothing that I type is echoed back to me. I've looked at the FreeBSD email archives and documentation and have not found anything that addresses these problems. I am grateful for any help that you can provide. David C.
