What's the reason for this? I'm not a serial interface expert,
so don't really understand all the issues.
FreeBSD-CURRENT has a driver called uplcom, which was ported from
NetBSD:
http://www.freebsd.org/cgi/cvsweb.cgi/src/share/man/man4/uplcom.4
It apparently can support USB serial adapters based on the
Prolific PL-2303 chipset, such as:
Aten UC-232A ( http://www.aten.com.tw/USB/USB_1/UC_232A.html )
ELECOM UC-SGT ( http://www2.elecom.co.jp/products/UC-SGT.html )
IOGEAR UC-232A ( http://www.iogear.com/products/product.php?Item=GUC232A )
Supposedly these cables do the RS-232 -> USB conversion, and as long
as you have the correct device driver, user-level applications
which use serial com ports should be able to use this.
Could this potentially work with gdb if I have:
- Legacy PC with serial port, running kernel, sending debug
messages to serial port
- New laptop with USB only, and no serial port, receiving
gdb debug messages over the serial adapter
