The edown
command reads file, or its standard input, one
"record" at a time, and transmits it down a serial line to a remote
evaluation board. After each record it transmits an ETX `0x03' and
then waits for an ACK `0x06' before continuing. If the ACK is not
forthcoming within a few seconds, or some other character is received,
then the transfer is stopped.
For most files a record is defined as everything up to (but not including) a Linefeed (or CR+LF on Windows). The only exception is for files in IDT/sim binary format, whose record format includes a length field.
-i
-r
-d dev

no default.
-s speed
DLBAUD
environment variable is used, but if neither is specified the speed
defaults to 9600 baud.
-T
edown
that it is being invoked
from the tip(1) `~C' command, and that it should use the
standard input and output file descriptors provided to it by
tip. This option is incompatible with the `-d' and `-s'
options above.
