Analyzing TCP/IP on serial port

[techie]

I have Ethereal and have tried Serial Monitor. Ethereal cant access serial port directly. Serial Monitor cant analyze protocols. Is there any program which can do both.

I have to test PPP-TCP/IP-HTTP over serial port. Can someone suggest how can I analyze PPP-TCP/IP packets travelling on serial port.

You can always trying using a lantronix device or build one yourself.

Any free ones like ethereal.

You can capture from a dial-up line with WinPCAP 3.1. Although 3.1 is still
beta, it seems to be reasonably stable.

IMPORTANT UPDATE: we have added an experimental support for capturing on PPP in WinPcap 3.1beta (the feature is available on Windows 2000/XP/2003, it does NOT work on NT4).

I am writing my own application that uses my own PPP and TCP/IP. This application does not use Windows TCP/IP stack and PPP stack. So there is no chance that WinPCAP will recognize it.

Wouldnt it be easy if Ethereal could read raw data from a file and then analyze it for protocols. There are many serial port capture programs that I can use to capture and save raw data to a file and Only if I could open a Raw Data file in Ethereal, I would be able to decode them.

From the Ethereal user guide 2.00:

The following file formats from other capture tools can be opened by Ethereal:
- libpcap, tcpdump and various other tools using tcpdump's capture format
- Sun snoop and atmsnoop
- Shomiti/Finisar Surveyor captures
- Novell LANalyzer captures
- Microsoft Network Monitor captures
- AIX's iptrace captures
- Cinco Networks NetXray captures
- Network Associates Windows-based Sniffer and Sniffer Pro captures
- Network General/Network Associates DOS-based Sniffer (compressed or unconpressed) captures
- AG Group/WildPackets EtherPeek/TokenPeek/AiroPeek/EtherHelp/PacketGrabber captures
- RADCOM's WAN/LAN Analyzer captures
- Network Instruments Observer version 9 captures
- Lucent/Ascend router debug output
- HP-UX's nettl
- Toshiba's ISDN routers dump output
- ISDN4BSD i4btrace utility
- traces from the EyeSDN USB S0
- IPLog format from the Cisco Secure Intrusion Detection System
- pppd logs (pppdump format)
- the output from VMS's TCPIPtrace/TCPtrace/UCX$TRACE utilities
- the text output from the DBS Etherwatch VMS utility
- Visual Networks' Visual UpTime traffic capture
- the output from CoSine L2 debug
- the output from Accellent's 5Views LAN agents
- Endace Measurement Systems' ERF format captures
- Linux Bluez Bluetooth stack hcidump -w traces

I captured a PPP packet containing IP datagram using another software. Then I converted it to Ethereal format by Text2Pcap utitliy. Now Etherial can open the packet but it defaults to ethernet packet. The first 12 bytes it always tries to use as MAC addresses.

How can tell ethereal that this packet is PPP and not an ethernet paclet.
