Has JRP opened the file with O_NDELAY? It won't work without (on modems). The
other thing you should check is that you are using a full set of wires on
your cable, in particular you should check that pin 5 and 6 are connected
straight thru.. The cable should like like (25->25 way).
2 -> 2
3 -> 3
4 -> 4 RTS
5 -> 5 CTS
6 -> 6 DSR
7 -> 7
8 -> 8 DCD
20 -> 20 DTR
experience shows that the most common problem with wiring on linux is pin 6
(DSR) isn't connected. It is important that all the standard signals are
connected if you intend to use a modem for input, you really _cannot_ get away
with a three wire circuit! Hardware flow control (you _are_ using HWFC?)
requires RTS and CTS to be connected. The usual way of detecting that the
modem has a valid connection is by it raising DCD, so you need that as well.
But if it works with minicom then either pin 8 isn't connected or JPR isn't
opening the device O_NDELAY.
This is required on 2.2.x kernels, you could get away with using cuaX on
2.0.x kernels and it would work.
