At this point, I just have a 'minicom' talking to a remote system through
a RS-232C port on '/dev/ttyS0'. At times I have typed character strings
(not echoed from the device) that appear to have locked up the port such
that further externally received input does not appear on the xterm
associated with that port. I hypothesize I have sent a character string
that changed the port's state. By rebooting the Linux box ('shutdown -r
now`) I get the port back, but there has to be a less disruptive way. I
want to reset the UART and any associated spool files, locks, and status
files, from my keyboard. Once I have a 'magic bullet', I'll make it an
alias or script - probably allowing one to select the brain-damaged port
(/dev/ttyS[0|1]). Whether I have correctly diagnosed the cause of my
problem, I would still like the capability.
Something like 'tput reset' down to capturing attention or the UART, I
suppose.
Any suggestions?
