I have a > TurboCom card that came with the TA, A TurboCOM would have been my immediate suggestion, so no joy there then {8^( To be honest, I'm not sure you'd notice the difference between 115k and 128k anyway; I went through this exercise and was disappointed in the results. It's pretty much OS dependent anyway; the best solution I eventually came up with was to bin the serial port TA and bought a LAN based ISDN gateway/router. Slightly more expensive, but fast to set up, uses ethernet (well understood and cheap), has no special serial port hardware and just *works*. I would sincerely hope that your TA is rate buffered (it should be; bin it if it ain't) and that your handshaking control is hardware based and properly functional. If so, then I would have thought it should be pretty much sufficient for most general needs.
