Problem: I cannot send AT commands to the modem. Commands such as:
$ echo "AT S0=5" > /dev/ttys2
don't cause the AA light to come on (Hayes). If I do it
under Kermit, it works fine but not from the command line.
What's going on? The modem is on (DOSspeak--->) "COM2".
There was a brief confusion on the SLS release about whether you should
be using /dev/ttys0 or /dev/ttys1 to address the "COM1" port. But the
SLS release now uses a zero-based numbering system, as does all of the
other releases out there, at least to my knowledge. So if you want to
access the "COM2" port, try using /dev/ttys1.
