TP 600,770 - Problems receiving a large file from a Hayes OPTIMA 28.8 modem using Z-modem or FTP with a V.42/V.42bis connection

Applicable to: World-Wide

Symptom:
If an NT Server with a Hayes OPTIMA 28.8 modem initiates a phone call to a ThinkPad 600 or 770 series machine with an ACP Modem, the ACP Modem will only be able to receive a small file (150 bytes) but not a larger file (1600 bytes) from the Hayes modem if the phone connection is made with the V.42 protocol.

This does not occur if an MNP connection is made between the two modems, or if the ThinkPad initiates the call.

Configuration:
This may occur on any ThinkPad 600 or 770 series ThinkPad with an ACP Modem.
Note: Not all ThinkPad 600's and 770's come with an ACP modem.
