The MCP215X parts you have received conform
functionally to the MCP2150 and MCP2155 device
data sheets (DS21655B and DS21690A), except for
the anomalies described below.
MCP215X Rev. C devices have addressed these
issues.

The MCP215X device will ignore queries from the
Primary device (PC, PDA) for the status of the
non-data circuits (CTS, RTS, DTR, DSR, CD, RI).
Work around
Do not have the Primary device application
request these signals for application operation.
Some new Palm
(TI OMAP31X) that sends a non-standard number
of BOFs (4) prior to parameter negotiation. The
MCP215X device expects 11 BOFs.
When the Primary device sends the SNRM
command (including the requested number of
BOFs (1) to use), the MCP215X responds with a
UA response using this number of BOFs (1). Since
the response only contains a single BOF, the TI
OMAP31X processors ignore this response.
Therefore, the communication link with the
Primary device is not established.
Work around
Do not use Palm PDAs that use the TI (OMAP310
and OMAP311) processor. Some of the Palm
PDAs that have this processor include the
Tungsten™ E, Zire™ 71 and Zire 21.
The Tungsten T2 (TI OMAP1510 with OS V5.2.1)
does not appear to have a connection issue with
the MCP215X device and, therefore, can be used
to establish a communication link with MCP215X
devices.
The MCP2140 could be used, since it can connect
to Palm PDAs that use this TI (OMAP310 and
OMAP311) processor.

3. Module: IR Protocol Handler
4. Module: IR Protocol Handler
The MCP215X IAS parser will supply LSAPSEL
response for more than just an IrDA:IrCOMM
LSAPSEL query. Some models of Pocket PC 2003
devices will issue an IrDA:IrObex LSAPSEL query
once the Pocket PC 2003 device has been
informed that its communicating with an IrCOMM
device. This causes the Ir link to not be established.
Work around
None for the MCP215X. However, the MCP2140
could be used and will respond to this Pocket PC
2003 IrDA:IrObex LSAPSEL query, allowing the Ir
link to be established.
The MCP215X may supply an RR response
instead of a TinyTP Credit response to a received
data packet.
Work around
None.
Note:
MCP215X
Currently, we have not observed any
loss of data or loss of communication
link when interfacing to other existing
IrDA
this issue.

... The values in the IrDA standard packet response would not reflect the value on the corresponding MCP2150 pin. The MCP2155 emulates the state of the CTS, RTS and DSR non-data circuits. These signals on the MCP2155 are used to interface with the embedded system’s host controller. The DTR, CD and RI signal values are communicated to the IrDA standard Primary device in an IrCOMM packet ...
