- Well, let me start be saying that I work for a University. We recently
- purchased 32 Multitech 28.8K rack mount modems, and have configured them
- SLIP/PPP.
-
- My only problem so far, is that when we enable the Hardware Flow
- control, or do have the XON/XOFF passed thru, we get unreliable
- connections. Meaning sometimes we connect and sometimes we don't. When
- we disable it, we always get connected, but some connections get very low
- throughput. So far, we have them configured with:
-
- &E1 - Sets it to V.42 Auto-reliable mode
- &E3 - means no modem-initiated flow control
- &E6 - means Xon/Xoff is NOT passed thru
- &E8 - Means Enq/Ack pacing on
- &E10 - means Normal Mode flow control off
- &E13 - means Pacing on
- &E15 - means data compression is enabled
-
- Now, with most machines, we don't have any problem. For example, my
- machine at home connects at 28.8K or 26.4K, and gets that same throughput
- when downloading or uploading. But, one machine doesn't get half of
- that, or even 1/3 of it. That machine is a MAC. And another machine
- connects at 14.4K and gets 9600 bps throughout. Of course, my machine at
- home uses a Multitech Desktop (which matches the rack mounts), and the
- MAC, I think, uses Teleport Gold. The other machine is a laptop which
- uses a Megahertz PCMCIA 14.4K.
-
- Does anyone have any suggestions? The guy who is on the MAC says he
- shouldn't have to change his modem strings to dial in, and doesn't have
- any problems dialing into another set of modems.
-
- Thanks in Advance..
