We attached a modem to the serial port on our SCO box
and removed the getty startup for /dev/tty1a from
the system startup.
stty 0 </dev/tty1a hangs
any attempt to access the line with Kermit hangs
cu -l/dev/tty1a -x9 produces the following:
Device Type Direct wanted
mlock tty1a succeeded
generic open failed, errno = 13
device was /dev/tty1a
getto ret -1
Connect failed: CAN'T ACCESS DEVICE
The first time we try
ls >/dev/tty1a it makes the lights flash on the modem
and turns on and leaves on DTR, and prints a message
about serial port garbage and possible loose cable.
the second time we try it, it hangs.
An suggestions on where to go next would be much appreciated.
