# 3.6. Linux Terminal on Palm (Handspring Visor) via IR

by Chris Morris on Linux/IrDA list: In addition to using IrDA to hotsync my Handspring Visor I got my Handspring visor to work as a Linux text terminal via infrared last night. My computer is a Dell Inspiron 3800 (BTW I wracked my brains for weeks trying to get IR to work. The whole problem was caused by Linux looking at the wrong IRQ for ttyS3 . ). I am using Beam Sync for Visor V1.0b2 by Hacker Dude-san (in Japanese) and MiniTerm (a former version of this HOWTO referred to it as MTerm) by Shigeyuki Seko . On the laptop I have IrDA set to SIR mode and COM 3 via BIOS. I have to set `/dev/ttyS3` to IRQ3 via setserial /dev/ttyS3 irq 3 on boot up. After boot up I do a:

    /sbin/modprobe irda
    /sbin/modprobe irtty
    /sbin/modprobe ircomm
    /sbin/ircomm-tty
    /usr/sbin/irattach /dev/ttyS3 -s

cat /proc/net/irda/discovery shows the visor as IrComm Now /etc/mgetty+fax/mgetty.conf has to have these options: port ttyS3 direct y speed 9600 , faster maybe possible but only 9600 worked for me so far toggle-dtr n Then in /etc/inittab: palm:235:respawn: /sbin/mgetty ircomm0 After all of this I can start MiniTerm, issue a '/sbin/init q' then send a few <CR> from the Visor and I get a text termianl login. While composing this email I found a previously undiscovered website that seems most helpful: palm-ppp-mini
