- Try using small MTU and MSS in CONFIG.TEL -- I suggest an MTU of 576 bytes and
- the corresponding MSS of 536 bytes. Load SLIP8250 with 5000 byte buffers, and
- enable hardware handshaking. Philip Burns of NWU wrote a version of SLIP8250
- that did better hardware handshaking than the distribution version 10 Crynwr
- release.
