I am lloking for synchronous serial adapters (V.35 or X.21)
for use with linux and synchronous leased line modems.
Are there any "best buy" cards, ie. cheap and standard?
I'm considering setting up a Linux system optimised as a router. The major
drawback to this idea is that I've failed to find any mention of
synchronous serial driver support for Linux, let alone X21 PCI or ISA
interface cards for the PC. Has anyone tried to do this?
