It's best to use the nearest mirror site, but here's the main
sites: Serial Software for Linux software for the serial ports
including getty and port monitors. Serial Communications for communication programs.
irqtune will give serial port interrupts higher
priority to improve performance. Using hdparm for hard-disk tuning
may help some more.
The Linux serial mailing list. To join, send email to email@example.com, with ``subscribe
linux-serial'' in the message body. If you send ``help'' in
the message body, you get a help message. The server also serves
many other Linux lists. Send the ``lists'' command for a list
of mailing lists.
Serial Suite by
Vern Hoxie is a collection of blurbs about the care and feeding of
the Linux serial port plus some simple programs. He also has a
Serial-Programming-HOWTO (not yet available from the Linux
Documentation Project). Your browser should automatically log you in
but if you do it manually login as "anonymous" and use your full
e-mail address as the password.
A white paper discussing serial communications and multiport
serial boards was available from Cyclades at http://www.cyclades.com.
