L — Get Line Number in the Current Source File
(Debugger Only)
N — Direct Download Via Current Debugger Port
122
The L command asks the terminal to indicate the source code line
number that the program is currently running. The debugging
computer can use this line number to locate and display the source
code for that line stored in the computer's disk drive.
The line number is sent as a two-byte binary value with the least
significant byte first.
Command Packet Received by Terminal:
<FFh> <55h> <count> L <CRC1> <CRC2>
Response Packet Sent by Terminal:
<FFh> <55h> <count> L <line number> <status> <CRC1>
<CRC2>
Where <status> is the status byte configured in the "T" command.
The N command sets up the terminal for a unit-receive direct
download through the current debugger port.
After the terminal has responded with the response packet (as shown
below), the terminal displays the message
ready for a direct download through the debugger port.
Then the serially attached computer may use ZONTALK 2000
protocol or the TXO Direct Load program (DL.exe) for the direct
download. When the download ends, the terminal restarts
automatically and begins running the new application program.
