- ===============================================================================
-
- I am interested in any recommendations people might have about modems
- for a particular application:
-
- running X Windows over standard analog telephone lines
-
- We use Graphon serial X terminals and high speed modems for home
- terminals. (Recently we evaluated the new NCD serial terminals also.)
- We also use an Annex III terminal server as the ethernet interface.
- This hardware provides a very inexpensive solution for putting X
- Windows on your desk at home as an extension of your work environment
- (do people still use standard tty terminals?).
-
- Our application demands a highly interactive environment - low delay
- on both sides, reasonably small buffering, etc. (I see a lot of
- messages flying around about modems for file transfers, and fax, but
- these type of data transfer applications have different requirements.)
- X windows is very consumptive of bandwidth: the data tends to be less
- amenable to compression and you tend to generate a lot of data per
- keystroke.
-
- We first started running X with 9600 Baud modems (before that it was
- impractical). We have been using v.32 modems for three years. I am
- about to purchase more modems for a modem pool in Japan, so I would
- like to reevaluate what is out there. With v.32 and v.42 modems here,
- and ISDN looming on the horizon, X windows over serial lines is
- getting really interesting.
-
- So here is my request:
-
- Please send me any information/feedback/opinions/etc. you might have
- about the best modem to use for this application.
-
- Here are some points of reference:
-
- Microcom QX/4232bis: Price: ~ $630 in US
-
- Great modems but probably at the top of the price range. Hard to
- purchase in Japan. Also, untested in Japan.
-
- Telebit T2500: Price: ~ $1000 in Japan
-
- We are having trouble with line drops - the modems will hang in the middle
- of a session.
-
- Telebit T3000: Price: Unknown
-
- Is this the same as a Worldblazer? We are currently testing these.
-
- OKI ????: Price: Less than a US modem, of course
-
- You quickly learn in Japan that the local vendors always try to sell
- you a domestic product that is cheaper and "just as good." Not
- scheduled to be tested (yet).
-
- Gandalf ISDN: Price: Unknown
-
- Not qualified in Japan yet. Appears to be the best solution on the
- horizon, but may be expensive.
-
- I will collect the responses and post the results. Please be sure to
- respond to picone@trdc.ti.com.
-
- I am particularly interested in some of these new, inexpensive v.32
- modems I keep reading about in this newsgroup. Is anyone using these
- in an X windows environment?
-
- Regards,
