Virtual Modem Details
The Serial Console Server’s Virtual Modem function emulates a hardware
modem to provide high speed serial modem functionality over an Ethernet
LAN or WAN using TCP/IP rather than over slower, less-reliable, telephone
lines.
AT Command Set Support
The Serial Console Server supports a subset of the standard Hayes command
set, as well as some extended commands, as shown in the following table:
Command Operation Response
+++ Return to command mode. The escape character
can be changed by modifying the S2 register.
none
A/ Repeat the last command string If successful: OK[CR][LF]
If failure: ERROR[CR][LF]
ATA[CR] Answer mode. Allow virtual modem to listen for a
TCP connection on the provided listen port: 5301.
If successful: OK[CR][LF]
If failure: ERROR[CR][LF]
ATD(T)
Remote
IP:Remote
Port[CR]
Try to establish a TCP connection and connect to
the specified remote host.
e.g. ATDT10.0.0.72:50001
Note: The SN3101 accepts T and P additions to
the ATD command, but ignores them.
If successful: CONNECT[CR][LF]
If connection failure:
NO CARRIER[CR][CF]
If other error:
ERROR[CR][LF]
ATEn[CR] Where n represents a numeric character (0 or 1.):
E0: disable command echo
E1: enable command echo
If successful: OK[CR][LF]
If failure: ERROR[CR][LF]

modem to data mode.
If an active TCP connection:
OK[CR][LF]
Otherwise:
ERROR[CR][LF]
