LG 5350 also, serial, more tips...
Authored by: tz on Dec 07, '02 07:03:20PM

The LG 5350 ($50 or so more than the Sanyo) via USB (if you can get the Sprint Cable - the LG has built-in USB and is recognized as a Qualcomm CDMA modem) also works, in this case "out of the box" though I use normal dialing with #777 in the phone number.

The LG also supports a serial port (more about that below), but no Sprint phone I know of has IrDA or BlueTooth. The PCMCIA card isn't covered in the same plan, it is $99/month for unlimited usage.

One note: Many people (including me) are reporting only getting 4 kilobytes per second or slower downloads. It depends on the location. Still, this is as good as many wired dialups and works almost anywhere.

The USB cable from sprint uses the USB standard colors (Red, Green, Black, Red and Shield) directly to the phone connector pins (5 pins including the shield). This cable either charges or maintains the LG's battery as well.

The LG also supports Serial (at 19200, 115200, and 230400) via a different cable (with electronics within), so it works with my Zaurus which I can turn into a wireless access point with some extra programs.

The LG doesn't support any kind of downloading or uploading of things like ringtones or images (Apparently the Sanyo can), nor does it have a speakerphone, but does have a monitor. Downloading can be done wirelessly if you can set up a server (or have your ISP add a thing or two to the mime types) and you read the developer's area of sprintpcs.com. The LG has well over 2 megabytes for such things (I have a 400K midi file from the classicalmusicarchives.com which plays on the polyphonic synth - the sound is good for a phone).

Conversely, the LG does support data calls and outbound (don't know about inbound) FAX, but these aren't included in the plan and are $0.35/minute. I.e. if you have a modem to your private network (or even ISP), you can do ATDT12345678901 and if a modem is found it will connect. Or if you have FCLASS 2.0 fax software on your computer it can similarly dial and transmit a fax. It can also receive data calls (there is a "data in" mode), i.e. a modem can dial YOUR computer. (this may also work for inbound fax, but I haven't got this working). This may or may not work on the Sanyo or other models.

Also, the charging cradle for the LG (a clamshell design - does data connection when closed) allows plugging in the data cable - apparently the Sanyo doesn't.

Other features like voice dialing or the voice memo recorder can be found from the manual - do a google search or go on sprintpcs.com for the PDF.

FYI, 777 is "PPP" on the keypad.

I've had some trouble with the serial, either having to turn DNS off or disabling VJ Header compression.

One other quirk is that it will "sleep" after about 20 seconds of inactivity. This can happen when a web page request takes longer than this to respond, or if you have an SSH session and don't type anything for a while. When "asleep", it will only wake up from the local end, so you may have to ping or tweak pppd to check the link more often to this to keep the pipe open, otherwise the remote end is likely to timeout.
