Sounds like you've dialed into a synchronous (BSC or possibly SDLC) port.
The vast majority of the communications cards available for PC's are
asynchronous and are unable to handle the requirements of synchronous
communications.  Assuming that you've attached the modem at the 4341 to
a 3705 communications controller or something similar, look in the
NCP (or PEP) sysgen input for a definition of 'LINECTL=SS' (LINE ConTroL
type Start-Stop).  If you have only synchoronous lines (and synchronous
modems attached to them) then you're out of luck unless you want to
pay mucho $$$ for a synchronous adapter card and modem, plus whatever
software is required to use them.

Hope this is of some use.
