The modem cable is properly shielded. The serial link runs at 115 k.
Is this really likely?
The router box at home is running 2.1.86. Is this perhaps causing
corruption?

BTW: I'm using CSLIP, not PPP. I don't get any more performance from
my serial link than what I did with earlier 2.1.x kernels (the one
before the TCP breakage).

I got 13 in the space of 50 minutes. All I was doing was reading email
(Emacs ViewMail over lbx) and transferred (rcp) two small files (one
around 9 kBytes and the other under 1 kByte).
