[syslinux] extlinux 6.03 serial console not responding to input

[Patrick Masotta]

>>>
 My question is whether the syslinux framework provides any
 way to flag errors in the configuration
 file.  The existing parsing code does not
 appear to make any attempt to detect or flag errors. 
 Otherwise, this atoi bug could have been
 caught much more easily -- there should have
 been a syntax error thrown by the parsing
 code.

 Thanks, but I'm not talking about
 debugging.  I'm talking about some way for
 syslinux to tell the user when there's a
 syntax error in the configuration
 file.

Your patch considers only a very particular case.
A systematic approach for "correctly" parsing a configuration file is not so simple.
It minimally requires a regular expression parser for format error detection plus
conversion & boundary checking when necessary. AFAIK this is not implemented yet;

Best,
