If you can change it, make sure your setup F1 "quick" menu shows
Host/Printer as being EIA/Para, and not Aux/EIA or anything else. This way,
your attached printer (if desired) won't interfere with either serial port.

Ctrl-<numeric "-"> will put you into the terminal setup where you can change
that.

Argh, it seems that perhaps my terminal only supports RS-422 on the "EIA"
port (or is that EIA-422?).

If I do a CTRL-<left arrow> to get to the application menu, then choose the
diag option, the EIA port is listed as 422 while the AUX port is listed as
232.

The manual for the 3153 is misleading. It says that the EIA port is 232 but
optionally also has 422 on the appropriate pins (meaning that the one
connector can speak both "protocols"). This doesn't seem to be the case in
my situation.

Thanks to all who responded.

Eric

Subject: Using the two ports on an IBM 3153 terminal

I have an IBM 3153 that I'm trying to use as a serial console for two
headless machines. The 3153 has an "AUX" and an "EIA" port. According to
its manual, one is DTE, one is DCE, but you can supposedly use both for
serial terminals (one just needs a null modem adapter, the other doesn't).

Well, I have one machine working on the AUX port with a null modem adapter.
The other port, no matter what I try, just doesn't seem to do anything. At
this

point, I don't suspect the terminal itself, I'm still thinking it's an
RS-232 issue.

Any ideas??

Eric
